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.)

1870 This installation shell script will examine your system and ask you questions
1871 to determine how the perl5 package should be installed. If you get
1872 stuck on a question, you may use a ! shell escape to start a subshell or
1873 execute a command. Many of the questions will have default answers in square
1874 brackets; typing carriage return will give you the default.
1876 On some of the questions which ask for file or directory names you are allowed
1877 to use the ~name construct to specify the login directory belonging to "name",
1878 even if you don't have a shell which knows about that. Questions where this is
1879 allowed will be marked "(~name ok)".
1883 dflt='Type carriage return to continue'
1887 The prompter used in this script allows you to use shell variables and
1888 backticks in your answers. You may use $1, $2, etc... to refer to the words
1889 in the default answer, as if the default line was a set of arguments given to a
1890 script shell. This means you may also use $* to repeat the whole default line,
1891 so you do not have to re-type everything to add something to the default.
1893 Everytime there is a substitution, you will have to confirm. If there is an
1894 error (e.g. an unmatched backtick), the default answer will remain unchanged
1895 and you will be prompted again.
1897 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1898 the questions and use the computed defaults (or the previous answers if there
1899 was already a config.sh file). Type 'Configure -h' for a list of options.
1900 You may also start interactively and then answer '& -d' at any prompt to turn
1901 on the non-interactive behaviour for the remainder of the execution.
1907 Much effort has been expended to ensure that this shell script will run on any
1908 Unix system. If despite that it blows up on yours, your best bet is to edit
1909 Configure and run it again. If you can't run Configure for some reason,
1910 you'll have to generate a config.sh file by hand. Whatever problems you
1911 have, let me (perlbug@perl.org) know how I blew it.
1913 This installation script affects things in two ways:
1915 1) it may do direct variable substitutions on some of the files included
1917 2) it builds a config.h file for inclusion in C programs. You may edit
1918 any of these files as the need arises after running this script.
1920 If you make a mistake on a question, there is no easy way to back up to it
1921 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1922 files. Configure will offer to let you do this before it runs the SH files.

5190 I can use $nm to extract the symbols from your C libraries. This
5191 is a time consuming task which may generate huge output on the disk (up
5192 to 3 megabytes) but that should make the symbols extraction faster. The
5193 alternative is to skip the 'nm' extraction part and to compile a small
5194 test program instead to determine whether each symbol is present. If
5195 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
5196 this may be the best solution.
