6 # (If you are trying to port this package to a machine without sh,
7 # I would suggest you have a look at the prototypical config_h.SH file
8 # and edit it to reflect your system. Some packages may include samples
9 # of config.h for certain machines, so you might look for one of those.)

14 # (Note: this Configure script was generated automatically. Rather than
15 # working with this copy of Configure, you may wish to get metaconfig.
16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
18 # you may fetch it yourself from your nearest archive site.)

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...]

1891 This is an UNSTABLE DEVELOPMENT release.
1892 The version of this $package distribution is $xversion, that is, odd,
1893 (as opposed to even) and that signifies a development release.
1894 If you want a maintenance release, you want an even-numbered version.
1896 Do ***NOT*** install this into production use.
1897 Data corruption and crashes are possible.
1899 It is most seriously suggested that you do not continue any further
1900 unless you want to help in developing and debugging Perl.
1902 If you *still* want to build perl, you can answer 'y' now,
1903 or pass -Dusedevel to Configure.

1952 This installation shell script will examine your system and ask you questions
1953 to determine how the perl5 package should be installed. If you get
1954 stuck on a question, you may use a ! shell escape to start a subshell or
1955 execute a command. Many of the questions will have default answers in square
1956 brackets; typing carriage return will give you the default.
1958 On some of the questions which ask for file or directory names you are allowed
1959 to use the ~name construct to specify the login directory belonging to "name",
1960 even if you don't have a shell which knows about that. Questions where this is
1961 allowed will be marked "(~name ok)".
1965 dflt='Type carriage return to continue'
1969 The prompter used in this script allows you to use shell variables and
1970 backticks in your answers. You may use $1, $2, etc... to refer to the words
1971 in the default answer, as if the default line was a set of arguments given to a
1972 script shell. This means you may also use $* to repeat the whole default line,
1973 so you do not have to re-type everything to add something to the default.
1975 Everytime there is a substitution, you will have to confirm. If there is an
1976 error (e.g. an unmatched backtick), the default answer will remain unchanged
1977 and you will be prompted again.
1979 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1980 the questions and use the computed defaults (or the previous answers if there
1981 was already a config.sh file). Type 'Configure -h' for a list of options.
1982 You may also start interactively and then answer '& -d' at any prompt to turn
1983 on the non-interactive behaviour for the remainder of the execution.
1989 Much effort has been expended to ensure that this shell script will run on any
1990 Unix system. If despite that it blows up on yours, your best bet is to edit
1991 Configure and run it again. If you can't run Configure for some reason,
1992 you'll have to generate a config.sh file by hand. Whatever problems you
1993 have, let me (perlbug@perl.org) know how I blew it.
1995 This installation script affects things in two ways:
1997 1) it may do direct variable substitutions on some of the files included
1999 2) it builds a config.h file for inclusion in C programs. You may edit
2000 any of these files as the need arises after running this script.
2002 If you make a mistake on a question, there is no easy way to back up to it
2003 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2004 files. Configure will offer to let you do this before it runs the SH files.
