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.)

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.)

1847 This is an UNSTABLE DEVELOPMENT release.
1848 The version of this $package distribution is $xversion, that is, odd,
1849 (as opposed to even) and that signifies a development release.
1850 If you want a maintenance release, you want an even-numbered version.
1852 Do ***NOT*** install this into production use.
1853 Data corruption and crashes are possible.
1855 It is most seriously suggested that you do not continue any further
1856 unless you want to help in developing and debugging Perl.
1858 If you *still* want to build perl, you can answer 'y' now,
1859 or pass -Dusedevel to Configure.

1908 This installation shell script will examine your system and ask you questions
1909 to determine how the perl5 package should be installed. If you get
1910 stuck on a question, you may use a ! shell escape to start a subshell or
1911 execute a command. Many of the questions will have default answers in square
1912 brackets; typing carriage return will give you the default.
1914 On some of the questions which ask for file or directory names you are allowed
1915 to use the ~name construct to specify the login directory belonging to "name",
1916 even if you don't have a shell which knows about that. Questions where this is
1917 allowed will be marked "(~name ok)".
1921 dflt='Type carriage return to continue'
1925 The prompter used in this script allows you to use shell variables and
1926 backticks in your answers. You may use $1, $2, etc... to refer to the words
1927 in the default answer, as if the default line was a set of arguments given to a
1928 script shell. This means you may also use $* to repeat the whole default line,
1929 so you do not have to re-type everything to add something to the default.
1931 Everytime there is a substitution, you will have to confirm. If there is an
1932 error (e.g. an unmatched backtick), the default answer will remain unchanged
1933 and you will be prompted again.
1935 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1936 the questions and use the computed defaults (or the previous answers if there
1937 was already a config.sh file). Type 'Configure -h' for a list of options.
1938 You may also start interactively and then answer '& -d' at any prompt to turn
1939 on the non-interactive behaviour for the remainder of the execution.
1945 Much effort has been expended to ensure that this shell script will run on any
1946 Unix system. If despite that it blows up on yours, your best bet is to edit
1947 Configure and run it again. If you can't run Configure for some reason,
1948 you'll have to generate a config.sh file by hand. Whatever problems you
1949 have, let me (perlbug@perl.org) know how I blew it.
1951 This installation script affects things in two ways:
1953 1) it may do direct variable substitutions on some of the files included
1955 2) it builds a config.h file for inclusion in C programs. You may edit
1956 any of these files as the need arises after running this script.
1958 If you make a mistake on a question, there is no easy way to back up to it
1959 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1960 files. Configure will offer to let you do this before it runs the SH files.

5251 I can use $nm to extract the symbols from your C libraries. This
5252 is a time consuming task which may generate huge output on the disk (up
5253 to 3 megabytes) but that should make the symbols extraction faster. The
5254 alternative is to skip the 'nm' extraction part and to compile a small
5255 test program instead to determine whether each symbol is present. If
5256 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
