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.)

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.)

29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1778 This installation shell script will examine your system and ask you questions
1779 to determine how the perl5 package should be installed. If you get
1780 stuck on a question, you may use a ! shell escape to start a subshell or
1781 execute a command. Many of the questions will have default answers in square
1782 brackets; typing carriage return will give you the default.
1784 On some of the questions which ask for file or directory names you are allowed
1785 to use the ~name construct to specify the login directory belonging to "name",
1786 even if you don't have a shell which knows about that. Questions where this is
1787 allowed will be marked "(~name ok)".
1791 dflt='Type carriage return to continue'
1795 The prompter used in this script allows you to use shell variables and
1796 backticks in your answers. You may use $1, $2, etc... to refer to the words
1797 in the default answer, as if the default line was a set of arguments given to a
1798 script shell. This means you may also use $* to repeat the whole default line,
1799 so you do not have to re-type everything to add something to the default.
1801 Everytime there is a substitution, you will have to confirm. If there is an
1802 error (e.g. an unmatched backtick), the default answer will remain unchanged
1803 and you will be prompted again.
1805 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1806 the questions and use the computed defaults (or the previous answers if there
1807 was already a config.sh file). Type 'Configure -h' for a list of options.
1808 You may also start interactively and then answer '& -d' at any prompt to turn
1809 on the non-interactive behaviour for the remainder of the execution.
1815 Much effort has been expended to ensure that this shell script will run on any
1816 Unix system. If despite that it blows up on yours, your best bet is to edit
1817 Configure and run it again. If you can't run Configure for some reason,
1818 you'll have to generate a config.sh file by hand. Whatever problems you
1819 have, let me (perlbug@perl.com) know how I blew it.
1821 This installation script affects things in two ways:
1823 1) it may do direct variable substitutions on some of the files included
1825 2) it builds a config.h file for inclusion in C programs. You may edit
1826 any of these files as the need arises after running this script.
1828 If you make a mistake on a question, there is no easy way to back up to it
1829 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1830 files. Configure will offer to let you do this before it runs the SH files.

2648 some known race conditions still remain. If you choose to try
2649 it, be very sure to not actually deploy it for production

5057 The installation process will also create a directory for
5058 vendor-supplied add-ons. Vendors who supply perl with their system
5059 may find it convenient to place all vendor-supplied files in this
5060 directory rather than in the main distribution directory. This will
5061 ease upgrades between binary-compatible maintenance versions of perl.
5063 Of course you may also use these directories in whatever way you see
5064 fit. For example, you might use them to access modules shared over a
5065 company-wide network.
5067 The default answer should be fine for most people.

6943 Previous version of $package used the standard IO mechanisms as defined
6944 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
6945 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
6946 the default. This abstraction layer can use AT&T's sfio (if you already
6947 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
6948 problems with some extension modules. Using PerlIO with stdio is safe,
6949 but it is slower than plain stdio and therefore is not the default.
6951 If this doesn't make any sense to you, just accept the default 'n'.
