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.code.sf.net/p/dist/code/trunk/dist
18 #
19 # Though this script was generated by metaconfig from metaunits, it is
20 # OK to send patches against Configure itself. It's up to the Configure
21 # pumpkin to backport the patch to the metaunits if it is accepted.
22 # For more information on patching Configure, see pod/perlhack.pod
23 #
24 # The metaunits are also available from the public git repository:
25 #     http://perl5.git.perl.org/metaconfig.git/ or
26 #     $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
27 #
28 # See Porting/pumpkin.pod for more information on metaconfig.

2247 This installation shell script will examine your system and ask you questions
2248 to determine how the perl5 package should be installed. If you get
2249 stuck on a question, you may use a ! shell escape to start a subshell or
2250 execute a command.  Many of the questions will have default answers in square
2251 brackets; typing carriage return will give you the default.
2252
2253 On some of the questions which ask for file or directory names you are allowed
2254 to use the ~name construct to specify the login directory belonging to "name",
2255 even if you don't have a shell which knows about that.  Questions where this is
2256 allowed will be marked "(~name ok)".

2263
2264 The prompter used in this script allows you to use shell variables and
2265 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2266 in the default answer, as if the default line was a set of arguments given to a
2267 script shell.  This means you may also use $* to repeat the whole default line,
2268 so you do not have to re-type everything to add something to the default.
2269
2270 Every time there is a substitution, you will have to confirm.  If there is an
2271 error (e.g. an unmatched backtick), the default answer will remain unchanged
2272 and you will be prompted again.
2273
2274 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2275 the questions and use the computed defaults (or the previous answers if there
2276 was already a config.sh file). Type 'Configure -h' for a list of options.
2277 You may also start interactively and then answer '& -d' at any prompt to turn
2278 on the non-interactive behaviour for the remainder of the execution.

2284 Much effort has been expended to ensure that this shell script will run on any
2285 Unix system.  If despite that it blows up on yours, your best bet is to edit
2286 Configure and run it again.  If you can't run Configure for some reason,
2287 you'll have to generate a config.sh file by hand.  Whatever problems you
2288 have, let me (perlbug@perl.org) know how I blew it.
2289
2290 This installation script affects things in two ways:
2291
2292 1) it may do direct variable substitutions on some of the files included
2293    in this kit.
2294 2) it builds a config.h file for inclusion in C programs.  You may edit
2295    any of these files as the need arises after running this script.
2296
2297 If you make a mistake on a question, there is no easy way to back up to it
2298 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2299 files.  Configure will offer to let you do this before it runs the SH files.
