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-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.

2191 This installation shell script will examine your system and ask you questions
2192 to determine how the perl5 package should be installed. If you get
2193 stuck on a question, you may use a ! shell escape to start a subshell or
2194 execute a command.  Many of the questions will have default answers in square
2195 brackets; typing carriage return will give you the default.
2196
2197 On some of the questions which ask for file or directory names you are allowed
2198 to use the ~name construct to specify the login directory belonging to "name",
2199 even if you don't have a shell which knows about that.  Questions where this is
2200 allowed will be marked "(~name ok)".
2201

2207
2208 The prompter used in this script allows you to use shell variables and
2209 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2210 in the default answer, as if the default line was a set of arguments given to a
2211 script shell.  This means you may also use $* to repeat the whole default line,
2212 so you do not have to re-type everything to add something to the default.
2213
2214 Everytime there is a substitution, you will have to confirm.  If there is an
2215 error (e.g. an unmatched backtick), the default answer will remain unchanged
2216 and you will be prompted again.
2217
2218 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2219 the questions and use the computed defaults (or the previous answers if there
2220 was already a config.sh file). Type 'Configure -h' for a list of options.
2221 You may also start interactively and then answer '& -d' at any prompt to turn
2222 on the non-interactive behaviour for the remainder of the execution.

2228 Much effort has been expended to ensure that this shell script will run on any
2229 Unix system.  If despite that it blows up on yours, your best bet is to edit
2230 Configure and run it again.  If you can't run Configure for some reason,
2231 you'll have to generate a config.sh file by hand.  Whatever problems you
2232 have, let me (perlbug@perl.org) know how I blew it.
2233
2234 This installation script affects things in two ways:
2235
2236 1) it may do direct variable substitutions on some of the files included
2237    in this kit.
2238 2) it builds a config.h file for inclusion in C programs.  You may edit
2239    any of these files as the need arises after running this script.
2240
2241 If you make a mistake on a question, there is no easy way to back up to it
2242 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2243 files.  Configure will offer to let you do this before it runs the SH files.
