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.)

1852 This installation shell script will examine your system and ask you questions
1853 to determine how the perl5 package should be installed. If you get
1854 stuck on a question, you may use a ! shell escape to start a subshell or
1855 execute a command. Many of the questions will have default answers in square
1856 brackets; typing carriage return will give you the default.
1858 On some of the questions which ask for file or directory names you are allowed
1859 to use the ~name construct to specify the login directory belonging to "name",
1860 even if you don't have a shell which knows about that. Questions where this is
1861 allowed will be marked "(~name ok)".
1865 dflt='Type carriage return to continue'
1869 The prompter used in this script allows you to use shell variables and
1870 backticks in your answers. You may use $1, $2, etc... to refer to the words
1871 in the default answer, as if the default line was a set of arguments given to a
1872 script shell. This means you may also use $* to repeat the whole default line,
1873 so you do not have to re-type everything to add something to the default.
1875 Everytime there is a substitution, you will have to confirm. If there is an
1876 error (e.g. an unmatched backtick), the default answer will remain unchanged
1877 and you will be prompted again.
1879 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1880 the questions and use the computed defaults (or the previous answers if there
1881 was already a config.sh file). Type 'Configure -h' for a list of options.
1882 You may also start interactively and then answer '& -d' at any prompt to turn
1883 on the non-interactive behaviour for the remainder of the execution.
1889 Much effort has been expended to ensure that this shell script will run on any
1890 Unix system. If despite that it blows up on yours, your best bet is to edit
1891 Configure and run it again. If you can't run Configure for some reason,
1892 you'll have to generate a config.sh file by hand. Whatever problems you
1893 have, let me (perlbug@perl.org) know how I blew it.
1895 This installation script affects things in two ways:
1897 1) it may do direct variable substitutions on some of the files included
1899 2) it builds a config.h file for inclusion in C programs. You may edit
1900 any of these files as the need arises after running this script.
1902 If you make a mistake on a question, there is no easy way to back up to it
1903 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1904 files. Configure will offer to let you do this before it runs the SH files.

2884 Perl can be built to take advantage of threads on some systems.
2885 To do so, Configure can be run with -Dusethreads.
2887 Note that threading is a highly experimental feature, and
2888 some known race conditions still remain. If you choose to try
2889 it, be very sure to not actually deploy it for production
2890 purposes. README.threads has more details, and is required
2891 reading if you enable threads.

2908 As of 5.5.640, Perl has two different internal threading implementations,
2909 the 5.005 version (5005threads) and an interpreter-based version
2910 (ithreads) that has one interpreter per thread. Both are very
2911 experimental. This arrangement exists to help developers work out
2912 which one is better.
2914 If you're a casual user, you probably don't want interpreter-threads
2915 at this time. There doesn't yet exist a way to create threads from
