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.)

1859 *** WHOA THERE!!! ***
1861 This is an UNSTABLE DEVELOPMENT release.
1862 The version of this $package distribution is $xversion, that is, odd,
1863 (as opposed to even) and that signifies a development release.
1864 If you want a maintenance release, you want an even-numbered version.
1866 Do ***NOT*** install this into production use.
1867 Data corruption and crashes are possible.
1869 It is most seriously suggested that you do not continue any further
1870 unless you want to help in developing and debugging Perl.
1872 If you *still* want to build perl, you can answer 'y' now,
1873 or pass -Dusedevel to Configure.

1922 This installation shell script will examine your system and ask you questions
1923 to determine how the perl5 package should be installed. If you get
1924 stuck on a question, you may use a ! shell escape to start a subshell or
1925 execute a command. Many of the questions will have default answers in square
1926 brackets; typing carriage return will give you the default.
1928 On some of the questions which ask for file or directory names you are allowed
1929 to use the ~name construct to specify the login directory belonging to "name",
1930 even if you don't have a shell which knows about that. Questions where this is
1931 allowed will be marked "(~name ok)".
1935 dflt='Type carriage return to continue'
1939 The prompter used in this script allows you to use shell variables and
1940 backticks in your answers. You may use $1, $2, etc... to refer to the words
1941 in the default answer, as if the default line was a set of arguments given to a
1942 script shell. This means you may also use $* to repeat the whole default line,
1943 so you do not have to re-type everything to add something to the default.
1945 Everytime there is a substitution, you will have to confirm. If there is an
1946 error (e.g. an unmatched backtick), the default answer will remain unchanged
1947 and you will be prompted again.
1949 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1950 the questions and use the computed defaults (or the previous answers if there
1951 was already a config.sh file). Type 'Configure -h' for a list of options.
1952 You may also start interactively and then answer '& -d' at any prompt to turn
1953 on the non-interactive behaviour for the remainder of the execution.
1959 Much effort has been expended to ensure that this shell script will run on any
1960 Unix system. If despite that it blows up on yours, your best bet is to edit
1961 Configure and run it again. If you can't run Configure for some reason,
1962 you'll have to generate a config.sh file by hand. Whatever problems you
1963 have, let me (perlbug@perl.org) know how I blew it.
1965 This installation script affects things in two ways:
1967 1) it may do direct variable substitutions on some of the files included
1969 2) it builds a config.h file for inclusion in C programs. You may edit
1970 any of these files as the need arises after running this script.
1972 If you make a mistake on a question, there is no easy way to back up to it
1973 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1974 files. Configure will offer to let you do this before it runs the SH files.

5267 I can use $nm to extract the symbols from your C libraries. This
5268 is a time consuming task which may generate huge output on the disk (up
5269 to 3 megabytes) but that should make the symbols extraction faster. The
5270 alternative is to skip the 'nm' extraction part and to compile a small
5271 test program instead to determine whether each symbol is present. If
5272 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
