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.)

1857 This installation shell script will examine your system and ask you questions
1858 to determine how the perl5 package should be installed. If you get
1859 stuck on a question, you may use a ! shell escape to start a subshell or
1860 execute a command. Many of the questions will have default answers in square
1861 brackets; typing carriage return will give you the default.
1863 On some of the questions which ask for file or directory names you are allowed
1864 to use the ~name construct to specify the login directory belonging to "name",
1865 even if you don't have a shell which knows about that. Questions where this is
1866 allowed will be marked "(~name ok)".
1870 dflt='Type carriage return to continue'
1874 The prompter used in this script allows you to use shell variables and
1875 backticks in your answers. You may use $1, $2, etc... to refer to the words
1876 in the default answer, as if the default line was a set of arguments given to a
1877 script shell. This means you may also use $* to repeat the whole default line,
1878 so you do not have to re-type everything to add something to the default.
1880 Everytime there is a substitution, you will have to confirm. If there is an
1881 error (e.g. an unmatched backtick), the default answer will remain unchanged
1882 and you will be prompted again.
1884 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1885 the questions and use the computed defaults (or the previous answers if there
1886 was already a config.sh file). Type 'Configure -h' for a list of options.
1887 You may also start interactively and then answer '& -d' at any prompt to turn
1888 on the non-interactive behaviour for the remainder of the execution.
1894 Much effort has been expended to ensure that this shell script will run on any
1895 Unix system. If despite that it blows up on yours, your best bet is to edit
1896 Configure and run it again. If you can't run Configure for some reason,
1897 you'll have to generate a config.sh file by hand. Whatever problems you
1898 have, let me (perlbug@perl.org) know how I blew it.
1900 This installation script affects things in two ways:
1902 1) it may do direct variable substitutions on some of the files included
1904 2) it builds a config.h file for inclusion in C programs. You may edit
1905 any of these files as the need arises after running this script.
1907 If you make a mistake on a question, there is no easy way to back up to it
1908 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1909 files. Configure will offer to let you do this before it runs the SH files.

2915 the 5.005 version (5005threads) and an interpreter-based version

2917 experimental. This arrangement exists to help developers work out
2918 which one is better.
