3# If these # comments don't work, trim them. Don't worry about any other
4# shell scripts, Configure will trim # comments from them for you.
5#
6# (If you are trying to port this package to a machine without sh,
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.)
10#
11# Yes, you may rip this off to use in other distribution packages. This
12# script belongs to the public domain and cannot be copyrighted.
13#
14# (Note: this Configure script was generated automatically. Rather than
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
dfe9444c
AD
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.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

40I will attempt to remedy the situation by running sh for you...

2304df62 1742This installation shell script will examine your system and ask you questions
a0d0e21e 1743to determine how the perl5 package should be installed. If you get
2304df62
AD
1744stuck on a question, you may use a ! shell escape to start a subshell or
1745execute a command. Many of the questions will have default answers in square
1746brackets; typing carriage return will give you the default.
1747
1748On some of the questions which ask for file or directory names you are allowed
1749to use the ~name construct to specify the login directory belonging to "name",
1750even if you don't have a shell which knows about that. Questions where this is
1751allowed will be marked "(~name ok)".

1756 . ./myread
1757 cat <<'EOH'
1758
1759The prompter used in this script allows you to use shell variables and
1760backticks in your answers. You may use $1, $2, etc... to refer to the words
1761in the default answer, as if the default line was a set of arguments given to a
1762script shell. This means you may also use $* to repeat the whole default line,
1763so you do not have to re-type everything to add something to the default.
1764
1765Everytime there is a substitution, you will have to confirm. If there is an
1766error (e.g. an unmatched backtick), the default answer will remain unchanged
1767and you will be prompted again.
1768
1769If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1770the questions and use the computed defaults (or the previous answers if there
1771was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1772You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1773on the non-interactive behaviour for the remainder of the execution.

1779Much effort has been expended to ensure that this shell script will run on any
1780Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1781Configure and run it again. If you can't run Configure for some reason,
1782you'll have to generate a config.sh file by hand. Whatever problems you

1785This installation script affects things in two ways:
1786
17871) it may do direct variable substitutions on some of the files included
1788 in this kit.
17892) 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.
1791
1792If you make a mistake on a question, there is no easy way to back up to it
1793currently. The easiest thing to do is to edit config.sh and rerun all the SH
1794files. Configure will offer to let you do this before it runs the SH files.
