1 #! /bin/sh

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 package (which contains metaconfig) is available via SVN:
17 #     svn co https://svn.sourceforge.net/svnroot/dist/trunk/dist
18 #
19 #
20 # Though this script was generated by metaconfig, it is OK to send
21 # patches against it. It's up to the Configure pumpkin to backport
22 # the patch to the metaunits if it is accepted.
23 # See Porting/pumpkin.pod for more information on metaconfig.

2192 This installation shell script will examine your system and ask you questions
2193 to determine how the perl5 package should be installed. If you get
2194 stuck on a question, you may use a ! shell escape to start a subshell or
2195 execute a command.  Many of the questions will have default answers in square
2196 brackets; typing carriage return will give you the default.
2197
2198 On some of the questions which ask for file or directory names you are allowed
2199 to use the ~name construct to specify the login directory belonging to "name",
2200 even if you don't have a shell which knows about that.  Questions where this is
2201 allowed will be marked "(~name ok)".

2208
2209 The prompter used in this script allows you to use shell variables and
2210 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2211 in the default answer, as if the default line was a set of arguments given to a
2212 script shell.  This means you may also use $* to repeat the whole default line,
2213 so you do not have to re-type everything to add something to the default.
2214
2215 Everytime there is a substitution, you will have to confirm.  If there is an
2216 error (e.g. an unmatched backtick), the default answer will remain unchanged
2217 and you will be prompted again.
2218
2219 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2220 the questions and use the computed defaults (or the previous answers if there
2221 was already a config.sh file). Type 'Configure -h' for a list of options.
2222 You may also start interactively and then answer '& -d' at any prompt to turn
2223 on the non-interactive behaviour for the remainder of the execution.

2229 Much effort has been expended to ensure that this shell script will run on any
2230 Unix system.  If despite that it blows up on yours, your best bet is to edit
2231 Configure and run it again.  If you can't run Configure for some reason,
2232 you'll have to generate a config.sh file by hand.  Whatever problems you
2233 have, let me (perlbug@perl.org) know how I blew it.
2234
2235 This installation script affects things in two ways:
2236
2237 1) it may do direct variable substitutions on some of the files included
2238    in this kit.
2239 2) it builds a config.h file for inclusion in C programs.  You may edit
2240    any of these files as the need arises after running this script.
2241
2242 If you make a mistake on a question, there is no easy way to back up to it
2243 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2244 files.  Configure will offer to let you do this before it runs the SH files.
