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...]

1885 This is an UNSTABLE DEVELOPMENT release.
1886 The version of this $package distribution is $xversion, that is, odd,
1887 (as opposed to even) and that signifies a development release.
1888 If you want a maintenance release, you want an even-numbered version.
1890 Do ***NOT*** install this into production use.
1891 Data corruption and crashes are possible.
1893 It is most seriously suggested that you do not continue any further
1894 unless you want to help in developing and debugging Perl.
1896 If you *still* want to build perl, you can answer 'y' now,
1897 or pass -Dusedevel to Configure.

1946 This installation shell script will examine your system and ask you questions
1947 to determine how the perl5 package should be installed. If you get
1948 stuck on a question, you may use a ! shell escape to start a subshell or
1949 execute a command. Many of the questions will have default answers in square
1950 brackets; typing carriage return will give you the default.
1952 On some of the questions which ask for file or directory names you are allowed
1953 to use the ~name construct to specify the login directory belonging to "name",
1954 even if you don't have a shell which knows about that. Questions where this is
1955 allowed will be marked "(~name ok)".
1959 dflt='Type carriage return to continue'
1963 The prompter used in this script allows you to use shell variables and
1964 backticks in your answers. You may use $1, $2, etc... to refer to the words
1965 in the default answer, as if the default line was a set of arguments given to a
1966 script shell. This means you may also use $* to repeat the whole default line,
1967 so you do not have to re-type everything to add something to the default.
1969 Everytime there is a substitution, you will have to confirm. If there is an
1970 error (e.g. an unmatched backtick), the default answer will remain unchanged
1971 and you will be prompted again.
1973 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1974 the questions and use the computed defaults (or the previous answers if there
1975 was already a config.sh file). Type 'Configure -h' for a list of options.
1976 You may also start interactively and then answer '& -d' at any prompt to turn
1977 on the non-interactive behaviour for the remainder of the execution.
1983 Much effort has been expended to ensure that this shell script will run on any
1984 Unix system. If despite that it blows up on yours, your best bet is to edit
1985 Configure and run it again. If you can't run Configure for some reason,
1986 you'll have to generate a config.sh file by hand. Whatever problems you
1987 have, let me (perlbug@perl.org) know how I blew it.
1989 This installation script affects things in two ways:
1991 1) it may do direct variable substitutions on some of the files included
1993 2) it builds a config.h file for inclusion in C programs. You may edit
1994 any of these files as the need arises after running this script.
1996 If you make a mistake on a question, there is no easy way to back up to it
1997 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1998 files. Configure will offer to let you do this before it runs the SH files.
