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.)

1885 This installation shell script will examine your system and ask you questions
1886 to determine how the perl5 package should be installed. If you get
1887 stuck on a question, you may use a ! shell escape to start a subshell or
1888 execute a command. Many of the questions will have default answers in square
1889 brackets; typing carriage return will give you the default.
1891 On some of the questions which ask for file or directory names you are allowed
1892 to use the ~name construct to specify the login directory belonging to "name",
1893 even if you don't have a shell which knows about that. Questions where this is
1894 allowed will be marked "(~name ok)".
1898 dflt='Type carriage return to continue'
1902 The prompter used in this script allows you to use shell variables and
1903 backticks in your answers. You may use $1, $2, etc... to refer to the words
1904 in the default answer, as if the default line was a set of arguments given to a
1905 script shell. This means you may also use $* to repeat the whole default line,
1906 so you do not have to re-type everything to add something to the default.
1908 Everytime there is a substitution, you will have to confirm. If there is an
1909 error (e.g. an unmatched backtick), the default answer will remain unchanged
1910 and you will be prompted again.
1912 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1913 the questions and use the computed defaults (or the previous answers if there
1914 was already a config.sh file). Type 'Configure -h' for a list of options.
1915 You may also start interactively and then answer '& -d' at any prompt to turn
1916 on the non-interactive behaviour for the remainder of the execution.
1922 Much effort has been expended to ensure that this shell script will run on any
1923 Unix system. If despite that it blows up on yours, your best bet is to edit
1924 Configure and run it again. If you can't run Configure for some reason,
1925 you'll have to generate a config.sh file by hand. Whatever problems you
1926 have, let me (perlbug@perl.org) know how I blew it.
1928 This installation script affects things in two ways:
1930 1) it may do direct variable substitutions on some of the files included
1932 2) it builds a config.h file for inclusion in C programs. You may edit
1933 any of these files as the need arises after running this script.
1935 If you make a mistake on a question, there is no easy way to back up to it
1936 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1937 files. Configure will offer to let you do this before it runs the SH files.

2918 Perl can be built to take advantage of threads on some systems.
2919 To do so, Configure can be run with -Dusethreads.
2921 Note that threading is a highly experimental feature, and
2922 some known race conditions still remain. If you choose to try
2923 it, be very sure to not actually deploy it for production
2924 purposes. README.threads has more details, and is required
2925 reading if you enable threads.

2942 As of 5.5.640, Perl has two different internal threading implementations,
2943 the 5.005 version (5005threads) and an interpreter-based version
2944 (ithreads) that has one interpreter per thread. Both are very
2945 experimental. This arrangement exists to help developers work out
2946 which one is better.
2948 If you're a casual user, you probably don't want interpreter-threads
2949 at this time. There doesn't yet exist a way to create threads from
2950 within Perl in this model, i.e., "use Thread;" will NOT work.

5217 I can use $nm to extract the symbols from your C libraries. This
5218 is a time consuming task which may generate huge output on the disk (up
5219 to 3 megabytes) but that should make the symbols extraction faster. The
5220 alternative is to skip the 'nm' extraction part and to compile a small
5221 test program instead to determine whether each symbol is present. If
5222 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
