28 SCO csh still thinks true is false. Write to SCO today and tell them that next
29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
32 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1096 This installation shell script will examine your system and ask you questions
1097 to determine how the perl5 package should be installed. If you get
1098 stuck on a question, you may use a ! shell escape to start a subshell or
1099 execute a command. Many of the questions will have default answers in square
1100 brackets; typing carriage return will give you the default.
1102 On some of the questions which ask for file or directory names you are allowed
1103 to use the ~name construct to specify the login directory belonging to "name",
1104 even if you don't have a shell which knows about that. Questions where this is
1105 allowed will be marked "(~name ok)".
1109 dflt='Type carriage return to continue'
1113 The prompter used in this script allows you to use shell variables and
1114 backticks in your answers. You may use $1, $2, etc... to refer to the words
1115 in the default answer, as if the default line was a set of arguments given to a
1116 script shell. This means you may also use $* to repeat the whole default line,
1117 so you do not have to re-type everything to add something to the default.
1119 Everytime there is a substitution, you will have to confirm. If there is an
1120 error (e.g. an unmatched backtick), the default answer will remain unchanged
1121 and you will be prompted again.
1123 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1124 the questions and use the computed defaults (or the previous answers if there
1125 was already a config.sh file). Type 'Configure -h' for a list of options.
1126 You may also start interactively and then answer '& -d' at any prompt to turn
1127 on the non-interactive behaviour for the remaining of the execution.
1133 Much effort has been expended to ensure that this shell script will run on any
1134 Unix system. If despite that it blows up on yours, your best bet is to edit
1135 Configure and run it again. If you can't run Configure for some reason,
1136 you'll have to generate a config.sh file by hand. Whatever problems you
1137 have, let me (lwall@netlabs.com) know how I blew it.
1139 This installation script affects things in two ways:
1141 1) it may do direct variable substitutions on some of the files included
1143 2) it builds a config.h file for inclusion in C programs. You may edit
1144 any of these files as the need arises after running this script.
1146 If you make a mistake on a question, there is no easy way to back up to it
1147 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1148 files. Configure will offer to let you do this before it runs the SH files.

4662 You can't have filenames longer than 14 chars. You can't even think about them!
