   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.)

  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.

  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.)
  19 #
  20 #
  21 # Though this script was generated by metaconfig, it is OK to send
  22 # patches against it. It's up to the Configure pumpkin to backport
  23 # the patch to the metaunits if it is accepted.
  24 # See Porting/pumpkin.pod for more information on metaconfig.

2193 This installation shell script will examine your system and ask you questions
2194 to determine how the perl5 package should be installed. If you get
2195 stuck on a question, you may use a ! shell escape to start a subshell or
2196 execute a command.  Many of the questions will have default answers in square
2197 brackets; typing carriage return will give you the default.
2198
2199 On some of the questions which ask for file or directory names you are allowed
2200 to use the ~name construct to specify the login directory belonging to "name",
2201 even if you don't have a shell which knows about that.  Questions where this is
2202 allowed will be marked "(~name ok)".

2210 The prompter used in this script allows you to use shell variables and
2211 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2212 in the default answer, as if the default line was a set of arguments given to a
2213 script shell.  This means you may also use $* to repeat the whole default line,
2214 so you do not have to re-type everything to add something to the default.
2215
2216 Everytime there is a substitution, you will have to confirm.  If there is an
2217 error (e.g. an unmatched backtick), the default answer will remain unchanged
2218 and you will be prompted again.
2219
2220 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2221 the questions and use the computed defaults (or the previous answers if there
2222 was already a config.sh file). Type 'Configure -h' for a list of options.
2223 You may also start interactively and then answer '& -d' at any prompt to turn
2224 on the non-interactive behaviour for the remainder of the execution.

2230 Much effort has been expended to ensure that this shell script will run on any
2231 Unix system.  If despite that it blows up on yours, your best bet is to edit
2232 Configure and run it again.  If you can't run Configure for some reason,
2233 you'll have to generate a config.sh file by hand.  Whatever problems you
2234 have, let me (perlbug@perl.org) know how I blew it.
2235
2236 This installation script affects things in two ways:
2237
2238 1) it may do direct variable substitutions on some of the files included
2239    in this kit.
2240 2) it builds a config.h file for inclusion in C programs.  You may edit
2241    any of these files as the need arises after running this script.
2242
2243 If you make a mistake on a question, there is no easy way to back up to it
2244 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2245 files.  Configure will offer to let you do this before it runs the SH files.
