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.)

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
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...]
39 OOPS! You naughty creature! You didn't run Configure with sh!
40 I will attempt to remedy the situation by running sh for you...

2120 This installation shell script will examine your system and ask you questions
2121 to determine how the perl5 package should be installed. If you get
2122 stuck on a question, you may use a ! shell escape to start a subshell or
2123 execute a command. Many of the questions will have default answers in square
2124 brackets; typing carriage return will give you the default.
2126 On some of the questions which ask for file or directory names you are allowed
2127 to use the ~name construct to specify the login directory belonging to "name",
2128 even if you don't have a shell which knows about that. Questions where this is
2129 allowed will be marked "(~name ok)".
2133 dflt='Type carriage return to continue'
2137 The prompter used in this script allows you to use shell variables and
2138 backticks in your answers. You may use $1, $2, etc... to refer to the words
2139 in the default answer, as if the default line was a set of arguments given to a
2140 script shell. This means you may also use $* to repeat the whole default line,
2141 so you do not have to re-type everything to add something to the default.
2143 Everytime there is a substitution, you will have to confirm. If there is an
2144 error (e.g. an unmatched backtick), the default answer will remain unchanged
2145 and you will be prompted again.
2147 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2148 the questions and use the computed defaults (or the previous answers if there
2149 was already a config.sh file). Type 'Configure -h' for a list of options.
2150 You may also start interactively and then answer '& -d' at any prompt to turn
2151 on the non-interactive behaviour for the remainder of the execution.
2157 Much effort has been expended to ensure that this shell script will run on any
2158 Unix system. If despite that it blows up on yours, your best bet is to edit
2159 Configure and run it again. If you can't run Configure for some reason,
2160 you'll have to generate a config.sh file by hand. Whatever problems you
2161 have, let me (perlbug@perl.org) know how I blew it.
2163 This installation script affects things in two ways:
2165 1) it may do direct variable substitutions on some of the files included
2167 2) it builds a config.h file for inclusion in C programs. You may edit
2168 any of these files as the need arises after running this script.
2170 If you make a mistake on a question, there is no easy way to back up to it
2171 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2172 files. Configure will offer to let you do this before it runs the SH files.
