- # If these # comments don't work, trim them. Don't worry about any other
- # shell scripts, Configure will trim # comments from them for you.
- #
- # (If you are trying to port this package to a machine without sh,
- # I would suggest you have a look at the prototypical config_h.SH file
- # and edit it to reflect your system. Some packages may include samples
- # of config.h for certain machines, so you might look for one of those.)
- #
- # Yes, you may rip this off to use in other distribution packages. This
- # script belongs to the public domain and cannot be copyrighted.
- #
- # (Note: this Configure script was generated automatically. Rather than
- # working with this copy of Configure, you may wish to get metaconfig.
- # The dist-3.0 package (which contains metaconfig) was posted in
- # comp.sources.misc so you may fetch it yourself from your nearest
- # archive site. Check with Archie if you don't know where that can be.)

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

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