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.)

1884 This installation shell script will examine your system and ask you questions
1885 to determine how the perl5 package should be installed. If you get
1886 stuck on a question, you may use a ! shell escape to start a subshell or
1887 execute a command. Many of the questions will have default answers in square
1888 brackets; typing carriage return will give you the default.
1890 On some of the questions which ask for file or directory names you are allowed
1891 to use the ~name construct to specify the login directory belonging to "name",
1892 even if you don't have a shell which knows about that. Questions where this is
1893 allowed will be marked "(~name ok)".
1897 dflt='Type carriage return to continue'
1901 The prompter used in this script allows you to use shell variables and
1902 backticks in your answers. You may use $1, $2, etc... to refer to the words
1903 in the default answer, as if the default line was a set of arguments given to a
1904 script shell. This means you may also use $* to repeat the whole default line,
1905 so you do not have to re-type everything to add something to the default.
1907 Everytime there is a substitution, you will have to confirm. If there is an
1908 error (e.g. an unmatched backtick), the default answer will remain unchanged
1909 and you will be prompted again.
1911 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1912 the questions and use the computed defaults (or the previous answers if there
1913 was already a config.sh file). Type 'Configure -h' for a list of options.
1914 You may also start interactively and then answer '& -d' at any prompt to turn
1915 on the non-interactive behaviour for the remainder of the execution.
1921 Much effort has been expended to ensure that this shell script will run on any
1922 Unix system. If despite that it blows up on yours, your best bet is to edit
1923 Configure and run it again. If you can't run Configure for some reason,
1924 you'll have to generate a config.sh file by hand. Whatever problems you
1925 have, let me (perlbug@perl.org) know how I blew it.
1927 This installation script affects things in two ways:
1929 1) it may do direct variable substitutions on some of the files included
1931 2) it builds a config.h file for inclusion in C programs. You may edit
1932 any of these files as the need arises after running this script.
1934 If you make a mistake on a question, there is no easy way to back up to it
1935 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1936 files. Configure will offer to let you do this before it runs the SH files.

2917 Perl can be built to take advantage of threads on some systems.
2918 To do so, Configure can be run with -Dusethreads.
2920 Note that threading is a highly experimental feature, and
2921 some known race conditions still remain. If you choose to try
2922 it, be very sure to not actually deploy it for production
2923 purposes. README.threads has more details, and is required
2924 reading if you enable threads.
2926 If this doesn't make any sense to you, just accept the default '$dflt'.

2941 As of 5.5.640, Perl has two different internal threading implementations,
2942 the 5.005 version (5005threads) and an interpreter-based version
2943 (ithreads) that has one interpreter per thread. Both are very
2944 experimental. This arrangement exists to help developers work out
2945 which one is better.
2947 If you're a casual user, you probably don't want interpreter-threads
2948 at this time. There doesn't yet exist a way to create threads from
2949 within Perl in this model, i.e., "use Thread;" will NOT work.

5216 I can use $nm to extract the symbols from your C libraries. This
5217 is a time consuming task which may generate huge output on the disk (up
5218 to 3 megabytes) but that should make the symbols extraction faster. The
5219 alternative is to skip the 'nm' extraction part and to compile a small
5220 test program instead to determine whether each symbol is present. If
5221 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
