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

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

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.)

1858 This installation shell script will examine your system and ask you questions
1859 to determine how the perl5 package should be installed. If you get
1860 stuck on a question, you may use a ! shell escape to start a subshell or
1861 execute a command. Many of the questions will have default answers in square
1862 brackets; typing carriage return will give you the default.
1864 On some of the questions which ask for file or directory names you are allowed
1865 to use the ~name construct to specify the login directory belonging to "name",
1866 even if you don't have a shell which knows about that. Questions where this is
1867 allowed will be marked "(~name ok)".
1871 dflt='Type carriage return to continue'
1875 The prompter used in this script allows you to use shell variables and
1876 backticks in your answers. You may use $1, $2, etc... to refer to the words
1877 in the default answer, as if the default line was a set of arguments given to a
1878 script shell. This means you may also use $* to repeat the whole default line,
1879 so you do not have to re-type everything to add something to the default.
1881 Everytime there is a substitution, you will have to confirm. If there is an
1882 error (e.g. an unmatched backtick), the default answer will remain unchanged
1883 and you will be prompted again.
1885 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1886 the questions and use the computed defaults (or the previous answers if there
1887 was already a config.sh file). Type 'Configure -h' for a list of options.
1888 You may also start interactively and then answer '& -d' at any prompt to turn
1889 on the non-interactive behaviour for the remainder of the execution.
1895 Much effort has been expended to ensure that this shell script will run on any
1896 Unix system. If despite that it blows up on yours, your best bet is to edit
1897 Configure and run it again. If you can't run Configure for some reason,
1898 you'll have to generate a config.sh file by hand. Whatever problems you
1899 have, let me (perlbug@perl.org) know how I blew it.
1901 This installation script affects things in two ways:
1903 1) it may do direct variable substitutions on some of the files included
1905 2) it builds a config.h file for inclusion in C programs. You may edit
1906 any of these files as the need arises after running this script.
1908 If you make a mistake on a question, there is no easy way to back up to it
1909 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1910 files. Configure will offer to let you do this before it runs the SH files.

2918 experimental. This arrangement exists to help developers work out
2919 which one is better.
