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.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1742 This installation shell script will examine your system and ask you questions
1743 to determine how the perl5 package should be installed. If you get
1744 stuck on a question, you may use a ! shell escape to start a subshell or
1745 execute a command. Many of the questions will have default answers in square
1746 brackets; typing carriage return will give you the default.
1748 On some of the questions which ask for file or directory names you are allowed
1749 to use the ~name construct to specify the login directory belonging to "name",
1750 even if you don't have a shell which knows about that. Questions where this is
1751 allowed will be marked "(~name ok)".
1755 dflt='Type carriage return to continue'
1759 The prompter used in this script allows you to use shell variables and
1760 backticks in your answers. You may use $1, $2, etc... to refer to the words
1761 in the default answer, as if the default line was a set of arguments given to a
1762 script shell. This means you may also use $* to repeat the whole default line,
1763 so you do not have to re-type everything to add something to the default.
1765 Everytime there is a substitution, you will have to confirm. If there is an
1766 error (e.g. an unmatched backtick), the default answer will remain unchanged
1767 and you will be prompted again.
1769 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1770 the questions and use the computed defaults (or the previous answers if there
1771 was already a config.sh file). Type 'Configure -h' for a list of options.
1772 You may also start interactively and then answer '& -d' at any prompt to turn
1773 on the non-interactive behaviour for the remainder of the execution.
1779 Much effort has been expended to ensure that this shell script will run on any
1780 Unix system. If despite that it blows up on yours, your best bet is to edit
1781 Configure and run it again. If you can't run Configure for some reason,
1782 you'll have to generate a config.sh file by hand. Whatever problems you
1783 have, let me (perlbug@perl.com) know how I blew it.
1785 This installation script affects things in two ways:
1787 1) it may do direct variable substitutions on some of the files included
1789 2) it builds a config.h file for inclusion in C programs. You may edit
1790 any of these files as the need arises after running this script.
1792 If you make a mistake on a question, there is no easy way to back up to it
1793 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1794 files. Configure will offer to let you do this before it runs the SH files.

4988 I can use $nm to extract the symbols from your C libraries. This
4989 is a time consuming task which may generate huge output on the disk (up
4990 to 3 megabytes) but that should make the symbols extraction faster. The
4991 alternative is to skip the 'nm' extraction part and to compile a small
