+

+found in the FAQ and at http:/www.perl.com) for a more recent version

+the subroutine name from writeMakefile to WriteMakefile and rerun
+'perl Makefile.PL', but you're most probably left alone, when you do

+It splits the task of generating the Makefile into several subroutines
+that can be individually overridden. Each subroutine returns the text
+it wishes to have written to the Makefile.
+MakeMaker is object oriented. Each directory below the current
+directory that contains a Makefile.PL. Is treated as a separate
+object. This makes it possible to write an unlimited number of
+Makefiles with a single invocation of WriteMakefile().

-# There is no .bs file supplied with the extension. Instead a _BS
-# file which has code for the special cases, like posix for berkeley db
-# on the NeXT.
-#
-# This file will get parsed, and produce a maybe empty
-# @DynaLoader::dl_resolve_using array for the current architecture.
-# That will be extended by $dynaloadlibs, which was computed by Andy's
-# extliblist script. If this array still is empty, we do nothing, else
-# we write a .bs file with an @DynaLoader::dl_resolve_using array, but
-# without any `if's, because there is no longer a need to deal with
-# special cases.
-#
-# The _BS file can put some code into the generated .bs file by placing
-# it in $bscode. This is a handy 'escape' mechanism that may prove
-# useful in complex situations.
-#
-# If @DynaLoader::dl_resolve_using contains -L* or -l* entries then
-# mkbootstrap will automatically add a dl_findfile() call to the

+
+=head2 Default Makefile Behaviour
+
+The generated Makefile enables the user of the extension to invoke
+
+ perl Makefile.PL # optionally "perl Makefile.PL verbose"
+ make
+ make test # optionally set TEST_VERBOSE=1
+ make install # See below
+
+The Makefile to be produced may be altered by adding arguments of the
+form C<KEY=VALUE>. E.g.
+
+ perl Makefile.PL PREFIX=/tmp/myperl5
+
+Other interesting targets in the generated Makefile are
+
+ make config # to check if the Makefile is up-to-date
+ make clean # delete local temp files (Makefile gets renamed)
+ make realclean # delete derived files (including ./blib)
+ make ci # check in all the files in the MANIFEST file
+ make dist # see below the Distribution Support section
+
+=head2 make test
+
+MakeMaker checks for the existence of a file named F<test.pl> in the
+current directory and if it exists it adds commands to the test target
+of the generated Makefile that will execute the script with the proper
+set of perl C<-I> options.
+
+MakeMaker also checks for any files matching glob("t/*.t"). It will
+add commands to the test target of the generated Makefile that execute
+all matching files via the L<Test::Harness> module with the C<-I>
+switches set correctly.
+
+=head2 make testdb
+
+A useful variation of the above is the target C<testdb>. It runs the
+test under the Perl debugger (see L<perldebug>). If the file
+F<test.pl> exists in the current directory, it is used for the test.
+
+If you want to debug some other testfile, set C<TEST_FILE> variable
+thusly:
+
+ make testdb TEST_FILE=t/mytest.t
+
+By default the debugger is called using C<-d> option to perl. If you
+want to specify some other option, set C<TESTDB_SW> variable:
+
+ make testdb TESTDB_SW=-Dx
+
+=head2 make install
+
+make alone puts all relevant files into directories that are named by
+the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR, and
+INST_MAN3DIR. All these default to something below ./blib if you are
+I<not> building below the perl source directory. If you I<are>
+building below the perl source, INST_LIB and INST_ARCHLIB default to
+ ../../lib, and INST_SCRIPT is not defined.
+
+The I<install> target of the generated Makefile copies the files found
+below each of the INST_* directories to their INSTALL*
+counterparts. Which counterparts are chosen depends on the setting of
+INSTALLDIRS according to the following table:
+
+ INSTALLDIRS set to
+ perl site
+
+ INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
+ INST_LIB INSTALLPRIVLIB INSTALLSITELIB
+ INST_BIN INSTALLBIN
+ INST_SCRIPT INSTALLSCRIPT
+ INST_MAN1DIR INSTALLMAN1DIR
+ INST_MAN3DIR INSTALLMAN3DIR
+
+The INSTALL... macros in turn default to their %Config
+($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
+
+You can check the values of these variables on your system with
+
+ perl '-V:install.*'
+
+And to check the sequence in which the library directories are
+searched by perl, run
+
+ perl -le 'print join $/, @INC'
+
+
+=head2 PREFIX and LIB attribute
+
+PREFIX and LIB can be used to set several INSTALL* attributes in one
+go. The quickest way to install a module in a non-standard place might
+be
+
+ perl Makefile.PL LIB=~/lib
+
+This will install the module's architecture-independent files into
+~/lib, the architecture-dependent files into ~/lib/$archname/auto.
+
+Another way to specify many INSTALL directories with a single
+parameter is PREFIX.
+
+ perl Makefile.PL PREFIX=~
+
+This will replace the string specified by $Config{prefix} in all
+$Config{install*} values.
+
+Note, that in both cases the tilde expansion is done by MakeMaker, not
+by perl by default, nor by make. Conflicts between parmeters LIB,
+PREFIX and the various INSTALL* arguments are resolved so that
+XXX
+
+If the user has superuser privileges, and is not working on AFS
+(Andrew File System) or relatives, then the defaults for
+INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate,
+and this incantation will be the best:
+
+ perl Makefile.PL; make; make test
+ make install
+
+make install per default writes some documentation of what has been
+done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
+can be bypassed by calling make pure_install.
+
+=head2 AFS users
+
+will have to specify the installation directories as these most
+probably have changed since perl itself has been installed. They will
+have to do this by calling
+
+ perl Makefile.PL INSTALLSITELIB=/afs/here/today \
+ INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
+ make
+
+Be careful to repeat this procedure every time you recompile an
+extension, unless you are sure the AFS installation directories are
+still valid.
+
+=head2 Static Linking of a new Perl Binary
+
+An extension that is built with the above steps is ready to use on
+systems supporting dynamic loading. On systems that do not support
+dynamic loading, any newly created extension has to be linked together
+with the available resources. MakeMaker supports the linking process
+by creating appropriate targets in the Makefile whenever an extension
+is built. You can invoke the corresponding section of the makefile with
+
+ make perl
+
+That produces a new perl binary in the current directory with all
+extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP,
+and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on
+UNIX, this is called Makefile.aperl (may be system dependent). If you
+want to force the creation of a new perl, it is recommended, that you
+delete this Makefile.aperl, so the directories are searched-through
+for linkable libraries again.
+
+The binary can be installed into the directory where perl normally
+resides on your machine with
+
+ make inst_perl
+
+To produce a perl binary with a different name than C<perl>, either say
+
+ perl Makefile.PL MAP_TARGET=myperl
+ make myperl
+ make inst_perl
+
+or say
+
+ perl Makefile.PL
+ make myperl MAP_TARGET=myperl
+ make inst_perl MAP_TARGET=myperl
+
+In any case you will be prompted with the correct invocation of the
+C<inst_perl> target that installs the new binary into INSTALLBIN.
+
+make inst_perl per default writes some documentation of what has been
+done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This
+can be bypassed by calling make pure_inst_perl.
+
+Warning: the inst_perl: target will most probably overwrite your
+existing perl binary. Use with care!
+
+Sometimes you might want to build a statically linked perl although
+your system supports dynamic loading. In this case you may explicitly
+set the linktype with the invocation of the Makefile.PL or make:
+
+ perl Makefile.PL LINKTYPE=static # recommended
+
+or
+
+ make LINKTYPE=static # works on most systems
+
+=head2 Determination of Perl Library and Installation Locations
+
+MakeMaker needs to know, or to guess, where certain things are
+located. Especially INST_LIB and INST_ARCHLIB (where to put the files
+during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read
+existing modules from), and PERL_INC (header files and C<libperl*.*>).
+
+Extensions may be built either using the contents of the perl source
+directory tree or from the installed perl library. The recommended way
+is to build extensions after you have run 'make install' on perl
+itself. You can do that in any directory on your hard disk that is not
+below the perl source tree. The support for extensions below the ext
+directory of the perl distribution is only good for the standard
+extensions that come with perl.
+
+If an extension is being built below the C<ext/> directory of the perl
+source then MakeMaker will set PERL_SRC automatically (e.g.,
+C<../..>). If PERL_SRC is defined and the extension is recognized as
+a standard extension, then other variables default to the following:
+
+ PERL_INC = PERL_SRC
+ PERL_LIB = PERL_SRC/lib
+ PERL_ARCHLIB = PERL_SRC/lib
+ INST_LIB = PERL_LIB
+ INST_ARCHLIB = PERL_ARCHLIB
+
+If an extension is being built away from the perl source then MakeMaker
+will leave PERL_SRC undefined and default to using the installed copy
+of the perl library. The other variables default to the following:
+
+ PERL_INC = $archlibexp/CORE
+ PERL_LIB = $privlibexp
+ PERL_ARCHLIB = $archlibexp
+ INST_LIB = ./blib/lib
+ INST_ARCHLIB = ./blib/arch
+
+If perl has not yet been installed then PERL_SRC can be defined on the
+command line as shown in the previous section.
+
+
+=head2 Which architecture dependent directory?
+
+If you don't want to keep the defaults for the INSTALL* macros,
+MakeMaker helps you to minimize the typing needed: the usual
+relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
+by Configure at perl compilation time. MakeMaker supports the user who
+sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
+then MakeMaker defaults the latter to be the same subdirectory of
+INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
+otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
+for INSTALLSITELIB and INSTALLSITEARCH.
+
+MakeMaker gives you much more freedom than needed to configure
+internal variables and get different results. It is worth to mention,
+that make(1) also lets you configure most of the variables that are
+used in the Makefile. But in the majority of situations this will not
+be necessary, and should only be done, if the author of a package
+recommends it (or you know what you're doing).
+
+=head2 Using Attributes and Parameters
+
+The following attributes can be specified as arguments to WriteMakefile()
+or as NAME=VALUE pairs on the command line:
+
+=cut
+
+# The following "=item C" is used by the attrib_help routine
+# likewise the "=back" below. So be careful when changing it!
+
+=over 2
+
+=item C
+
+Ref to array of *.c file names. Initialised from a directory scan
+and the values portion of the XS attribute hash. This is not
+currently used by MakeMaker but may be handy in Makefile.PLs.
+
+=item CCFLAGS
+
+String that will be included in the compiler call command line between
+the arguments INC and OPTIMIZE.
+
+=item CONFIG
+
+Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from
+config.sh. MakeMaker will add to CONFIG the following values anyway:
+ar
+cc
+cccdlflags
+ccdlflags
+dlext
+dlsrc
+ld
+lddlflags
+ldflags
+libc
+lib_ext
+obj_ext
+ranlib
+sitelibexp
+sitearchexp
+so
+
+=item CONFIGURE
+
+CODE reference. The subroutine should return a hash reference. The
+hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to
+be determined by some evaluation method.
+
+=item DEFINE
+
+Something like C<"-DHAVE_UNISTD_H">
+
+=item DIR
+
+Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
+] in ext/SDBM_File
+
+=item DISTNAME
+
+Your name for distributing the package (by tar file). This defaults to
+NAME above.
+
+=item DL_FUNCS
+
+Hashref of symbol names for routines to be made available as
+universal symbols. Each key/value pair consists of the package name
+and an array of routine names in that package. Used only under AIX
+(export lists) and VMS (linker options) at present. The routine
+names supplied will be expanded in the same way as XSUB names are
+expanded by the XS() macro. Defaults to
+
+ {"$(NAME)" => ["boot_$(NAME)" ] }
+
+e.g.
+
+ {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
+ "NetconfigPtr" => [ 'DESTROY'] }
+
+=item DL_VARS
+
+Array of symbol names for variables to be made available as
+universal symbols. Used only under AIX (export lists) and VMS
+(linker options) at present. Defaults to []. (e.g. [ qw(
+Foo_version Foo_numstreams Foo_tree ) ])
+
+=item EXCLUDE_EXT
+
+Array of extension names to exclude when doing a static build. This
+is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more
+details. (e.g. [ qw( Socket POSIX ) ] )
+
+This attribute may be most useful when specified as a string on the
+commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe'
+
+=item EXE_FILES
+
+Ref to array of executable files. The files will be copied to the
+INST_SCRIPT directory. Make realclean will delete them from there
+again.
+
+=item NO_VC
+
+In general any generated Makefile checks for the current version of
+MakeMaker and the version the Makefile was built under. If NO_VC is
+set, the version check is neglected. Do not write this into your
+Makefile.PL, use it interactively instead.
+
+=item FIRST_MAKEFILE
+
+The name of the Makefile to be produced. Defaults to the contents of
+MAKEFILE, but can be overridden. This is used for the second Makefile
+that will be produced for the MAP_TARGET.
+
+=item FULLPERL
+
+Perl binary able to run this extension.
+
+=item H
+
+Ref to array of *.h file names. Similar to C.
+
+=item IMPORTS
+
+IMPORTS is only used on OS/2.
+
+=item INC
+
+Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">
+
+=item INCLUDE_EXT
+
+Array of extension names to be included when doing a static build.
+MakeMaker will normally build with all of the installed extensions when
+doing a static build, and that is usually the desired behavior. If
+INCLUDE_EXT is present then MakeMaker will build only with those extensions
+which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ])
+
+It is not necessary to mention DynaLoader or the current extension when
+filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then
+only DynaLoader and the current extension will be included in the build.
+
+This attribute may be most useful when specified as a string on the
+commandline: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek'
+
+=item INSTALLARCHLIB
+
+Used by 'make install', which copies files from INST_ARCHLIB to this
+directory if INSTALLDIRS is set to perl.
+
+=item INSTALLBIN
+
+Directory to install binary files (e.g. tkperl) into.
+
+=item INSTALLDIRS
+
+Determines which of the two sets of installation directories to
+choose: installprivlib and installarchlib versus installsitelib and
+installsitearch. The first pair is chosen with INSTALLDIRS=perl, the
+second with INSTALLDIRS=site. Default is site.
+
+=item INSTALLMAN1DIR
+
+This directory gets the man pages at 'make install' time. Defaults to
+$Config{installman1dir}.
+
+=item INSTALLMAN3DIR
+
+This directory gets the man pages at 'make install' time. Defaults to
+$Config{installman3dir}.
+
+=item INSTALLPRIVLIB
+
+Used by 'make install', which copies files from INST_LIB to this
+directory if INSTALLDIRS is set to perl.
+
+=item INSTALLSCRIPT
+
+Used by 'make install' which copies files from INST_SCRIPT to this
+directory.
+
+=item INSTALLSITELIB
+
+Used by 'make install', which copies files from INST_LIB to this
+directory if INSTALLDIRS is set to site (default).
+
+=item INSTALLSITEARCH
+
+Used by 'make install', which copies files from INST_ARCHLIB to this
+directory if INSTALLDIRS is set to site (default).
+
+=item INST_ARCHLIB
+
+Same as INST_LIB for architecture dependent files.
+
+=item INST_BIN
+
+Directory to put real binary files during 'make'. These will be copied
+to INSTALLBIN during 'make install'
+
+=item INST_EXE
+
+Old name for INST_SCRIPT. Deprecated. Please use INST_SCRIPT if you
+need to use it.
+
+=item INST_LIB
+
+Directory where we put library files of this extension while building
+it.
+
+=item INST_MAN1DIR
+
+Directory to hold the man pages at 'make' time
+
+=item INST_MAN3DIR
+
+Directory to hold the man pages at 'make' time
+
+=item INST_SCRIPT
+
+Directory, where executable files should be installed during
+'make'. Defaults to "./blib/bin", just to have a dummy location during
+testing. make install will copy the files in INST_SCRIPT to
+INSTALLSCRIPT.
+
+=item LDFROM
+
+defaults to "$(OBJECT)" and is used in the ld command to specify
+what files to link/load from (also see dynamic_lib below for how to
+specify ld flags)
+
+=item LIBPERL_A
+
+The filename of the perllibrary that will be used together with this
+extension. Defaults to libperl.a.
+
+=item LIB
+
+LIB can only be set at C<perl Makefile.PL> time. It has the effect of
+setting both INSTALLPRIVLIB and INSTALLSITELIB to that value regardless any
+
+=item LIBS
+
+An anonymous array of alternative library
+specifications to be searched for (in order) until
+at least one library is found. E.g.
+
+ 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]
+
+Mind, that any element of the array
+contains a complete set of arguments for the ld
+command. So do not specify
+
+ 'LIBS' => ["-ltcl", "-ltk", "-lX11"]
+
+See ODBM_File/Makefile.PL for an example, where an array is needed. If
+you specify a scalar as in
+
+ 'LIBS' => "-ltcl -ltk -lX11"
+
+MakeMaker will turn it into an array with one element.
+
+=item LINKTYPE
+
+'static' or 'dynamic' (default unless usedl=undef in
+config.sh). Should only be used to force static linking (also see
+linkext below).
+
+=item MAKEAPERL
+
+Boolean which tells MakeMaker, that it should include the rules to
+make a perl. This is handled automatically as a switch by
+MakeMaker. The user normally does not need it.
+
+=item MAKEFILE
+
+The name of the Makefile to be produced.
+
+=item MAN1PODS
+
+Hashref of pod-containing files. MakeMaker will default this to all
+EXE_FILES files that include POD directives. The files listed
+here will be converted to man pages and installed as was requested
+at Configure time.
+
+=item MAN3PODS
+
+Hashref of .pm and .pod files. MakeMaker will default this to all
+ .pod and any .pm files that include POD directives. The files listed
+here will be converted to man pages and installed as was requested
+at Configure time.
+
+=item MAP_TARGET
+
+If it is intended, that a new perl binary be produced, this variable
+may hold a name for that binary. Defaults to perl
+
+=item MYEXTLIB
+
+If the extension links to a library that it builds set this to the
+name of the library (see SDBM_File)
+
+=item NAME
+
+Perl module name for this extension (DBD::Oracle). This will default
+to the directory name but should be explicitly defined in the
+Makefile.PL.
+
+=item NEEDS_LINKING
+
+MakeMaker will figure out, if an extension contains linkable code
+anywhere down the directory tree, and will set this variable
+accordingly, but you can speed it up a very little bit, if you define
+this boolean variable yourself.
+
+=item NOECHO
+
+Defaults to C<@>. By setting it to an empty string you can generate a
+Makefile that echos all commands. Mainly used in debugging MakeMaker
+itself.
+
+=item NORECURS
+
+Boolean. Attribute to inhibit descending into subdirectories.
+
+=item OBJECT
+
+List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long
+string containing all object files, e.g. "tkpBind.o
+tkpButton.o tkpCanvas.o"
+
+=item OPTIMIZE
+
+Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
+passed to subdirectory makes.
+
+=item PERL
+
+Perl binary for tasks that can be done by miniperl
+
+=item PERLMAINCC
+
+The call to the program that is able to compile perlmain.c. Defaults
+to $(CC).
+
+=item PERL_ARCHLIB
+
+Same as above for architecture dependent files
+
+=item PERL_LIB
+
+Directory containing the Perl library to use.
+
+=item PERL_SRC
+
+Directory containing the Perl source code (use of this should be
+avoided, it may be undefined)
+
+=item PL_FILES
+
+Ref to hash of files to be processed as perl programs. MakeMaker
+will default to any found *.PL file (except Makefile.PL) being keys
+and the basename of the file being the value. E.g.
+
+ {'foobar.PL' => 'foobar'}
+
+The *.PL files are expected to produce output to the target files
+themselves.
+
+=item PM
+
+Hashref of .pm files and *.pl files to be installed. e.g.
+
+ {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'}
+
+By default this will include *.pm and *.pl and the files found in
+the PMLIBDIRS directories. Defining PM in the
+Makefile.PL will override PMLIBDIRS.
+
+=item PMLIBDIRS
+
+Ref to array of subdirectories containing library files. Defaults to
+[ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files
+they contain will be installed in the corresponding location in the
+library. A libscan() method can be used to alter the behaviour.
+Defining PM in the Makefile.PL will override PMLIBDIRS.
+
+=item PREFIX
+
+Can be used to set the three INSTALL* attributes in one go (except for
+probably INSTALLMAN1DIR, if it is not below PREFIX according to
+%Config). They will have PREFIX as a common directory node and will
+branch from that node into lib/, lib/ARCHNAME or whatever Configure
+decided at the build time of your perl (unless you override one of
+them, of course).
+
+=item PREREQ_PM
+
+Hashref: Names of modules that need to be available to run this
+extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the
+desired version is the value. If the required version number is 0, we
+only check if any version is installed already.
+
+=item SKIP
+
+Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the
+Makefile. Caution! Do not use the SKIP attribute for the neglectible
+speedup. It may seriously damage the resulting Makefile. Only use it,
+if you really need it.
+
+=item TYPEMAPS
+
+Ref to array of typemap file names. Use this when the typemaps are
+in some directory other than the current directory or when they are
+not named B<typemap>. The last typemap in the list takes
+precedence. A typemap in the current directory has highest
+precedence, even if it isn't listed in TYPEMAPS. The default system
+typemap has lowest precedence.
+
+=item VERSION
+
+Your version number for distributing the package. This defaults to
+0.1.
+
+=item VERSION_FROM
+
+Instead of specifying the VERSION in the Makefile.PL you can let
+MakeMaker parse a file to determine the version number. The parsing
+routine requires that the file named by VERSION_FROM contains one
+single line to compute the version number. The first line in the file
+that contains the regular expression
+
+ /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/
+
+will be evaluated with eval() and the value of the named variable
+B<after> the eval() will be assigned to the VERSION attribute of the
+MakeMaker object. The following lines will be parsed o.k.:
+
+ $VERSION = '1.00';
+ *VERSION = \'1.01';
+ ( $VERSION ) = '$Revision: 1.216 $ ' =~ /\$Revision:\s+([^\s]+)/;
+ $FOO::VERSION = '1.10';
+ *FOO::VERSION = \'1.11';
+
+but these will fail:
+
+ my $VERSION = '1.01';
+ local $VERSION = '1.02';
+ local $FOO::VERSION = '1.30';
+
+The file named in VERSION_FROM is not added as a dependency to
+Makefile. This is not really correct, but it would be a major pain
+during development to have to rewrite the Makefile for any smallish
+change in that file. If you want to make sure that the Makefile
+contains the correct VERSION macro after any change of the file, you
+would have to do something like
+
+ depend => { Makefile => '$(VERSION_FROM)' }
+
+See attribute C<depend> below.
+
+=item XS
+
+Hashref of .xs files. MakeMaker will default this. e.g.
+
+ {'name_of_file.xs' => 'name_of_file.c'}
+
+The .c files will automatically be included in the list of files
+deleted by a make clean.
+
+=item XSOPT
+
+String of options to pass to xsubpp. This might include C<-C++> or
+C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for
+that purpose.
+
+=item XSPROTOARG
+
+May be set to an empty string, which is identical to C<-prototypes>, or
+C<-noprototypes>. See the xsubpp documentation for details. MakeMaker
+defaults to the empty string.
+
+=item XS_VERSION
+
+Your version number for the .xs file of this package. This defaults
+to the value of the VERSION attribute.

+If you specify COMPRESS, then SUFFIX should also be altered, as it is

+'ln', which links the file, and 'best' which copies symbolic links and

+=head2 Overriding MakeMaker Methods
+
+If you cannot achieve the desired Makefile behaviour by specifying
+attributes you may define private subroutines in the Makefile.PL.
+Each subroutines returns the text it wishes to have written to
+the Makefile. To override a section of the Makefile you can
+either say:
+
+ sub MY::c_o { "new literal text" }
+
+or you can edit the default by saying something like:
+
+ sub MY::c_o {
+ package MY; # so that "SUPER" works right
+ my $inherited = shift->SUPER::c_o(@_);
+ $inherited =~ s/old text/new text/;
+ $inherited;
}
- # write extra code if *_BS says so
- print BS $DynaLoader::bscode if $DynaLoader::bscode;
- print BS "1;\n";
- close BS;
- }
- if ($Config{'dlsrc'} =~ /^dl_aix/){
- open AIX, ">$att{BASEEXT}.exp";
- print AIX "#!\nboot_$att{BASEEXT}\n";
- close AIX;
+If you running experiments with embedding perl as a library into other
+applications, you might find MakeMaker not sufficient. You'd better
+have a look at ExtUtils::embed which is a collection of utilities for
+embedding.
+
+If you still need a different solution, try to develop another
+subroutine, that fits your needs and submit the diffs to
+F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.
+
+For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>.
+
+Here is a simple example of how to add a new target to the generated
+Makefile:
+
+ sub MY::postamble {
+ '
+ $(MYEXTLIB): sdbm/Makefile
+ cd sdbm && $(MAKE) all
+ ';
}

+=head2 Hintsfile support
+
+MakeMaker.pm uses the architecture specific information from
+Config.pm. In addition it evaluates architecture specific hints files
+in a C<hints/> directory. The hints files are expected to be named
+like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
+name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
+MakeMaker within the WriteMakefile() subroutine, and can be used to
+execute commands as well as to include special variables. The rules
+which hintsfile is chosen are the same as in Configure.
+
+The hintsfile is eval()ed immediately after the arguments given to
+WriteMakefile are stuffed into a hash reference $self but before this
+reference becomes blessed. So if you want to do the equivalent to
+override or create an attribute you would say something like
+
+ $self->{LIBS} = ['-ldbm -lucb -lc'];
+
+=head2 Distribution Support
+
+For authors of extensions MakeMaker provides several Makefile
+targets. Most of the support comes from the ExtUtils::Manifest module,
+where additional documentation can be found.
+
+=over 4
+
+=item make distcheck
+
+reports which files are below the build directory but not in the
+MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
+details)
+
+=item make skipcheck
+
+reports which files are skipped due to the entries in the
+C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
+details)
+
+=item make distclean
+
+does a realclean first and then the distcheck. Note that this is not
+needed to build a new distribution as long as you are sure, that the
+MANIFEST file is ok.
+
+=item make manifest
+
+rewrites the MANIFEST file, adding all remaining files found (See
+ExtUtils::Manifest::mkmanifest() for details)
+
+=item make distdir
+
+Copies all the files that are in the MANIFEST file to a newly created
+directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
+exists, it will be removed first.
+
+=item make disttest
+
+Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
+a make test in that directory.
+
+=item make tardist
+
+First does a distdir. Then a command $(PREOP) which defaults to a null
+command, followed by $(TOUNIX), which defaults to a null command under
+UNIX, and will convert files in distribution directory to UNIX format
+otherwise. Next it runs C<tar> on that directory into a tarfile and
+deletes the directory. Finishes with a command $(POSTOP) which
+defaults to a null command.
+
+=item make dist
+
+Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
+
+=item make uutardist
+
+Runs a tardist first and uuencodes the tarfile.
+
+=item make shdist
+
+First does a distdir. Then a command $(PREOP) which defaults to a null
+command. Next it runs C<shar> on that directory into a sharfile and
+deletes the intermediate directory again. Finishes with a command
+$(POSTOP) which defaults to a null command. Note: For shdist to work
+properly a C<shar> program that can handle directories is mandatory.
+
+=item make zipdist
+
+First does a distdir. Then a command $(PREOP) which defaults to a null
+command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a
+zipfile. Then deletes that directory. Finishes with a command
+$(POSTOP) which defaults to a null command.
+
+=item make ci
+
+Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
+
+=back
+
+Customization of the dist targets can be done by specifying a hash
+reference to the dist attribute of the WriteMakefile call. The
+following parameters are recognized:
+
+ CI ('ci -u')
+ COMPRESS ('compress')
+ POSTOP ('@ :')
+ PREOP ('@ :')
+ TO_UNIX (depends on the system)
+ RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
+ SHAR ('shar')
+ SUFFIX ('Z')
+ TAR ('tar')
+ TARFLAGS ('cvf')
+ ZIP ('zip')
+ ZIPFLAGS ('-r')
+
+An example:
+
+ WriteMakefile( 'dist' => { COMPRESS=>"gzip", SUFFIX=>"gz" })
+
+=head2 Disabling an extension
+
+If some events detected in F<Makefile.PL> imply that there is no way
+to create the Module, but this is a normal state of things, then you
+can create a F<Makefile> which does nothing, but succeeds on all the
+"usual" build targets. To do so, use
+
+ ExtUtils::MakeMaker::WriteEmptyMakefile();
+
+instead of WriteMakefile().
+
+This may be useful if other modules expect this module to be I<built>
+OK, as opposed to I<work> OK (say, this system-dependent module builds
+in a subdirectory of some other distribution, or is listed as a
+dependency in a CPAN::Bundle, but the functionality is supported by
+different means on the current architecture).
