7 # I would suggest you have a look at the prototypical config_h.SH file
8 # and edit it to reflect your system. Some packages may include samples
9 # of config.h for certain machines, so you might look for one of those.)

15 # working with this copy of Configure, you may wish to get metaconfig.
16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
18 # you may fetch it yourself from your nearest archive site.)

29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

2056 This installation shell script will examine your system and ask you questions
2057 to determine how the perl5 package should be installed. If you get
2058 stuck on a question, you may use a ! shell escape to start a subshell or
2059 execute a command. Many of the questions will have default answers in square
2060 brackets; typing carriage return will give you the default.
2062 On some of the questions which ask for file or directory names you are allowed
2063 to use the ~name construct to specify the login directory belonging to "name",
2064 even if you don't have a shell which knows about that. Questions where this is
2065 allowed will be marked "(~name ok)".
2069 dflt='Type carriage return to continue'
2073 The prompter used in this script allows you to use shell variables and
2074 backticks in your answers. You may use $1, $2, etc... to refer to the words
2075 in the default answer, as if the default line was a set of arguments given to a
2076 script shell. This means you may also use $* to repeat the whole default line,
2077 so you do not have to re-type everything to add something to the default.
2079 Everytime there is a substitution, you will have to confirm. If there is an
2080 error (e.g. an unmatched backtick), the default answer will remain unchanged
2081 and you will be prompted again.
2083 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2084 the questions and use the computed defaults (or the previous answers if there
2085 was already a config.sh file). Type 'Configure -h' for a list of options.
2086 You may also start interactively and then answer '& -d' at any prompt to turn
2087 on the non-interactive behaviour for the remainder of the execution.
2093 Much effort has been expended to ensure that this shell script will run on any
2094 Unix system. If despite that it blows up on yours, your best bet is to edit
2095 Configure and run it again. If you can't run Configure for some reason,
2096 you'll have to generate a config.sh file by hand. Whatever problems you
2097 have, let me (perlbug@perl.org) know how I blew it.
2099 This installation script affects things in two ways:
2101 1) it may do direct variable substitutions on some of the files included
2103 2) it builds a config.h file for inclusion in C programs. You may edit
2104 any of these files as the need arises after running this script.
2106 If you make a mistake on a question, there is no easy way to back up to it
2107 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2108 files. Configure will offer to let you do this before it runs the SH files.

7207 Perl can be built with extra modules or bundles of modules which
7208 will be fetched from the CPAN and installed alongside Perl.
7210 Notice that you will need access to the CPAN; either via the Internet,
7211 or a local copy, for example a CD-ROM or a local CPAN mirror. (You will
7212 be asked later to configure the CPAN.pm module which will in turn do
7213 the installation of the rest of the extra modules or bundles.)
7215 Notice also that if the modules require any external software such as
7216 libraries and headers (the libz library and the zlib.h header for the
7217 Compress::Zlib module, for example) you MUST have any such software
7218 already installed, this configuration process will NOT install such
7221 If this doesn't make any sense to you, just accept the default '$dflt'.
