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.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1823 This installation shell script will examine your system and ask you questions
1824 to determine how the perl5 package should be installed. If you get
1825 stuck on a question, you may use a ! shell escape to start a subshell or
1826 execute a command. Many of the questions will have default answers in square
1827 brackets; typing carriage return will give you the default.
1829 On some of the questions which ask for file or directory names you are allowed
1830 to use the ~name construct to specify the login directory belonging to "name",
1831 even if you don't have a shell which knows about that. Questions where this is
1832 allowed will be marked "(~name ok)".
1836 dflt='Type carriage return to continue'
1840 The prompter used in this script allows you to use shell variables and
1841 backticks in your answers. You may use $1, $2, etc... to refer to the words
1842 in the default answer, as if the default line was a set of arguments given to a
1843 script shell. This means you may also use $* to repeat the whole default line,
1844 so you do not have to re-type everything to add something to the default.
1846 Everytime there is a substitution, you will have to confirm. If there is an
1847 error (e.g. an unmatched backtick), the default answer will remain unchanged
1848 and you will be prompted again.
1850 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1851 the questions and use the computed defaults (or the previous answers if there
1852 was already a config.sh file). Type 'Configure -h' for a list of options.
1853 You may also start interactively and then answer '& -d' at any prompt to turn
1854 on the non-interactive behaviour for the remainder of the execution.
1860 Much effort has been expended to ensure that this shell script will run on any
1861 Unix system. If despite that it blows up on yours, your best bet is to edit
1862 Configure and run it again. If you can't run Configure for some reason,
1863 you'll have to generate a config.sh file by hand. Whatever problems you
1864 have, let me (perlbug@perl.com) know how I blew it.
1866 This installation script affects things in two ways:
1868 1) it may do direct variable substitutions on some of the files included
1870 2) it builds a config.h file for inclusion in C programs. You may edit
1871 any of these files as the need arises after running this script.
1873 If you make a mistake on a question, there is no easy way to back up to it
1874 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1875 files. Configure will offer to let you do this before it runs the SH files.

5113 : see if setuid scripts can be secure
5116 Some kernels have a bug that prevents setuid #! scripts from being
5117 secure. Some sites have disabled setuid #! scripts because of this.
5119 First let's decide if your kernel supports secure setuid #! scripts.
5120 (If setuid #! scripts would be secure but have been disabled anyway,
5121 don't say that they are secure if asked.)

5135 If you are not sure if they are secure, I can check but I'll need a
5136 username and password different from the one you are using right now.

5201 setuid scripts cannot be secure. On systems where setuid scripts have
5202 been disabled, the setuid/setgid bits on scripts are currently
5203 useless. It is possible for $package to detect those bits and emulate
5204 setuid/setgid in a secure fashion. This emulation will only work if
5205 setuid scripts have been disabled in your kernel.

5414 elsewhere under a different prefix.
5416 If you do not wish to put everything under a single prefix, that's
5417 ok. You will be prompted for the individual locations; this siteprefix
5418 is only used to suggest the defaults.
