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

2061 This installation shell script will examine your system and ask you questions
2062 to determine how the perl5 package should be installed. If you get
2063 stuck on a question, you may use a ! shell escape to start a subshell or
2064 execute a command. Many of the questions will have default answers in square
2065 brackets; typing carriage return will give you the default.
2067 On some of the questions which ask for file or directory names you are allowed
2068 to use the ~name construct to specify the login directory belonging to "name",
2069 even if you don't have a shell which knows about that. Questions where this is
2070 allowed will be marked "(~name ok)".
2074 dflt='Type carriage return to continue'
2078 The prompter used in this script allows you to use shell variables and
2079 backticks in your answers. You may use $1, $2, etc... to refer to the words
2080 in the default answer, as if the default line was a set of arguments given to a
2081 script shell. This means you may also use $* to repeat the whole default line,
2082 so you do not have to re-type everything to add something to the default.
2084 Everytime there is a substitution, you will have to confirm. If there is an
2085 error (e.g. an unmatched backtick), the default answer will remain unchanged
2086 and you will be prompted again.
2088 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2089 the questions and use the computed defaults (or the previous answers if there
2090 was already a config.sh file). Type 'Configure -h' for a list of options.
2091 You may also start interactively and then answer '& -d' at any prompt to turn
2092 on the non-interactive behaviour for the remainder of the execution.
2098 Much effort has been expended to ensure that this shell script will run on any
2099 Unix system. If despite that it blows up on yours, your best bet is to edit
2100 Configure and run it again. If you can't run Configure for some reason,
2101 you'll have to generate a config.sh file by hand. Whatever problems you
2102 have, let me (perlbug@perl.org) know how I blew it.
2104 This installation script affects things in two ways:
2106 1) it may do direct variable substitutions on some of the files included
2108 2) it builds a config.h file for inclusion in C programs. You may edit
2109 any of these files as the need arises after running this script.
2111 If you make a mistake on a question, there is no easy way to back up to it
2112 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2113 files. Configure will offer to let you do this before it runs the SH files.
