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

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.)

1878 This is an UNSTABLE DEVELOPMENT release.
1879 The version of this $package distribution is $xversion, that is, odd,
1880 (as opposed to even) and that signifies a development release.
1881 If you want a maintenance release, you want an even-numbered version.
1883 Do ***NOT*** install this into production use.
1884 Data corruption and crashes are possible.
1886 It is most seriously suggested that you do not continue any further
1887 unless you want to help in developing and debugging Perl.
1889 If you *still* want to build perl, you can answer 'y' now,
1890 or pass -Dusedevel to Configure.

1939 This installation shell script will examine your system and ask you questions
1940 to determine how the perl5 package should be installed. If you get
1941 stuck on a question, you may use a ! shell escape to start a subshell or
1942 execute a command. Many of the questions will have default answers in square
1943 brackets; typing carriage return will give you the default.
1945 On some of the questions which ask for file or directory names you are allowed
1946 to use the ~name construct to specify the login directory belonging to "name",
1947 even if you don't have a shell which knows about that. Questions where this is
1948 allowed will be marked "(~name ok)".
1952 dflt='Type carriage return to continue'
1956 The prompter used in this script allows you to use shell variables and
1957 backticks in your answers. You may use $1, $2, etc... to refer to the words
1958 in the default answer, as if the default line was a set of arguments given to a
1959 script shell. This means you may also use $* to repeat the whole default line,
1960 so you do not have to re-type everything to add something to the default.
1962 Everytime there is a substitution, you will have to confirm. If there is an
1963 error (e.g. an unmatched backtick), the default answer will remain unchanged
1964 and you will be prompted again.
1966 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1967 the questions and use the computed defaults (or the previous answers if there
1968 was already a config.sh file). Type 'Configure -h' for a list of options.
1969 You may also start interactively and then answer '& -d' at any prompt to turn
1970 on the non-interactive behaviour for the remainder of the execution.
1976 Much effort has been expended to ensure that this shell script will run on any
1977 Unix system. If despite that it blows up on yours, your best bet is to edit
1978 Configure and run it again. If you can't run Configure for some reason,
1979 you'll have to generate a config.sh file by hand. Whatever problems you
1980 have, let me (perlbug@perl.org) know how I blew it.
1982 This installation script affects things in two ways:
1984 1) it may do direct variable substitutions on some of the files included
1986 2) it builds a config.h file for inclusion in C programs. You may edit
1987 any of these files as the need arises after running this script.
1989 If you make a mistake on a question, there is no easy way to back up to it
1990 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1991 files. Configure will offer to let you do this before it runs the SH files.
