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.)

1883 This installation shell script will examine your system and ask you questions
1884 to determine how the perl5 package should be installed. If you get
1885 stuck on a question, you may use a ! shell escape to start a subshell or
1886 execute a command. Many of the questions will have default answers in square
1887 brackets; typing carriage return will give you the default.
1889 On some of the questions which ask for file or directory names you are allowed
1890 to use the ~name construct to specify the login directory belonging to "name",
1891 even if you don't have a shell which knows about that. Questions where this is
1892 allowed will be marked "(~name ok)".
1896 dflt='Type carriage return to continue'
1900 The prompter used in this script allows you to use shell variables and
1901 backticks in your answers. You may use $1, $2, etc... to refer to the words
1902 in the default answer, as if the default line was a set of arguments given to a
1903 script shell. This means you may also use $* to repeat the whole default line,
1904 so you do not have to re-type everything to add something to the default.
1906 Everytime there is a substitution, you will have to confirm. If there is an
1907 error (e.g. an unmatched backtick), the default answer will remain unchanged
1908 and you will be prompted again.
1910 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1911 the questions and use the computed defaults (or the previous answers if there
1912 was already a config.sh file). Type 'Configure -h' for a list of options.
1913 You may also start interactively and then answer '& -d' at any prompt to turn
1914 on the non-interactive behaviour for the remainder of the execution.
1920 Much effort has been expended to ensure that this shell script will run on any
1921 Unix system. If despite that it blows up on yours, your best bet is to edit
1922 Configure and run it again. If you can't run Configure for some reason,
1923 you'll have to generate a config.sh file by hand. Whatever problems you
1924 have, let me (perlbug@perl.org) know how I blew it.
1926 This installation script affects things in two ways:
1928 1) it may do direct variable substitutions on some of the files included
1930 2) it builds a config.h file for inclusion in C programs. You may edit
1931 any of these files as the need arises after running this script.
1933 If you make a mistake on a question, there is no easy way to back up to it
1934 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1935 files. Configure will offer to let you do this before it runs the SH files.

2916 Perl can be built to take advantage of threads on some systems.
2917 To do so, Configure can be run with -Dusethreads.
2919 Note that threading is a highly experimental feature, and
2920 some known race conditions still remain. If you choose to try
2921 it, be very sure to not actually deploy it for production
2922 purposes. README.threads has more details, and is required
2923 reading if you enable threads.

2940 As of 5.5.640, Perl has two different internal threading implementations,
2941 the 5.005 version (5005threads) and an interpreter-based version
2942 (ithreads) that has one interpreter per thread. Both are very
2943 experimental. This arrangement exists to help developers work out
2944 which one is better.
2946 If you're a casual user, you probably don't want interpreter-threads
2947 at this time. There doesn't yet exist a way to create threads from

5215 I can use $nm to extract the symbols from your C libraries. This
5216 is a time consuming task which may generate huge output on the disk (up
5217 to 3 megabytes) but that should make the symbols extraction faster. The
