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

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

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.)

1843 The version of this $package distribution is $xversion, that is, odd,
1844 (as opposed to even) and that signifies a development release.
1845 If you want a maintenance release, you want an even-numbered version.
1847 Do ***NOT*** install this into production use.
1848 Data corruption and crashes are possible.
1850 It is most seriously suggested that you do not continue any further
1851 unless you want to help in developing and debugging Perl.
1853 If you *still* want to build perl, you can answer 'y' now,
1854 or pass -Dusedevel to Configure.

1903 This installation shell script will examine your system and ask you questions
1904 to determine how the perl5 package should be installed. If you get
1905 stuck on a question, you may use a ! shell escape to start a subshell or
1906 execute a command. Many of the questions will have default answers in square
1907 brackets; typing carriage return will give you the default.
1909 On some of the questions which ask for file or directory names you are allowed
1910 to use the ~name construct to specify the login directory belonging to "name",
1911 even if you don't have a shell which knows about that. Questions where this is
1912 allowed will be marked "(~name ok)".
1916 dflt='Type carriage return to continue'
1920 The prompter used in this script allows you to use shell variables and
1921 backticks in your answers. You may use $1, $2, etc... to refer to the words
1922 in the default answer, as if the default line was a set of arguments given to a
1923 script shell. This means you may also use $* to repeat the whole default line,
1924 so you do not have to re-type everything to add something to the default.
1926 Everytime there is a substitution, you will have to confirm. If there is an
1927 error (e.g. an unmatched backtick), the default answer will remain unchanged
1928 and you will be prompted again.
1930 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1931 the questions and use the computed defaults (or the previous answers if there
1932 was already a config.sh file). Type 'Configure -h' for a list of options.
1933 You may also start interactively and then answer '& -d' at any prompt to turn
1934 on the non-interactive behaviour for the remainder of the execution.
1940 Much effort has been expended to ensure that this shell script will run on any
1941 Unix system. If despite that it blows up on yours, your best bet is to edit
1942 Configure and run it again. If you can't run Configure for some reason,
1943 you'll have to generate a config.sh file by hand. Whatever problems you
1944 have, let me (perlbug@perl.org) know how I blew it.
1946 This installation script affects things in two ways:
1948 1) it may do direct variable substitutions on some of the files included
1950 2) it builds a config.h file for inclusion in C programs. You may edit
1951 any of these files as the need arises after running this script.
1953 If you make a mistake on a question, there is no easy way to back up to it
1954 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1955 files. Configure will offer to let you do this before it runs the SH files.
