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.)

1854 This installation shell script will examine your system and ask you questions
1855 to determine how the perl5 package should be installed. If you get
1856 stuck on a question, you may use a ! shell escape to start a subshell or
1857 execute a command. Many of the questions will have default answers in square
1858 brackets; typing carriage return will give you the default.
1860 On some of the questions which ask for file or directory names you are allowed
1861 to use the ~name construct to specify the login directory belonging to "name",
1862 even if you don't have a shell which knows about that. Questions where this is
1863 allowed will be marked "(~name ok)".
1867 dflt='Type carriage return to continue'
1871 The prompter used in this script allows you to use shell variables and
1872 backticks in your answers. You may use $1, $2, etc... to refer to the words
1873 in the default answer, as if the default line was a set of arguments given to a
1874 script shell. This means you may also use $* to repeat the whole default line,
1875 so you do not have to re-type everything to add something to the default.
1877 Everytime there is a substitution, you will have to confirm. If there is an
1878 error (e.g. an unmatched backtick), the default answer will remain unchanged
1879 and you will be prompted again.
1881 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1882 the questions and use the computed defaults (or the previous answers if there
1883 was already a config.sh file). Type 'Configure -h' for a list of options.
1884 You may also start interactively and then answer '& -d' at any prompt to turn
1885 on the non-interactive behaviour for the remainder of the execution.
1891 Much effort has been expended to ensure that this shell script will run on any
1892 Unix system. If despite that it blows up on yours, your best bet is to edit
1893 Configure and run it again. If you can't run Configure for some reason,
1894 you'll have to generate a config.sh file by hand. Whatever problems you
1895 have, let me (perlbug@perl.org) know how I blew it.
1897 This installation script affects things in two ways:
1899 1) it may do direct variable substitutions on some of the files included
1901 2) it builds a config.h file for inclusion in C programs. You may edit
1902 any of these files as the need arises after running this script.
1904 If you make a mistake on a question, there is no easy way to back up to it
1905 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1906 files. Configure will offer to let you do this before it runs the SH files.

2911 As of 5.5.640, Perl has two different internal threading implementations,
2912 the 5.005 version (5005threads) and an interpreter-based version
2913 (ithreads) that has one interpreter per thread. Both are very
2914 experimental. This arrangement exists to help developers work out
2915 which one is better.
2917 If you're a casual user, you probably don't want interpreter-threads
