# A tool to build a perl release tarball
# Very basic but functional - if you're on a unix system.
#
# If you're on Win32 then it should still work, but various Unix command-line
# tools will need to be available somewhere. An obvious choice is to install
# Cygwin and ensure its 'bin' folder is on the PATH in the shell where you run
# this script. The Cygwin 'bin' folder needs to precede the Windows 'system32'
# folder so that Cygwin's 'find' command is found in preference to the Windows
# 'find' command. Your Cygwin installation will need to contain at least the
# 'cpio' command, in addition to the commands installed by default, and it will
# also be useful to have 'curl' and 'diffstat' installed too for later stages
# of the release process (namely, Porting\corelist.pl and generating the commit
# statistics for the perlXYZdelta.pod file respectively). Finally, ensure that
# the 'awk' and 'shasum' commands are copies of gawk.exe and sha1sum.exe
# respectively, rather the links to them that only work in a Cygwin bash shell
# which they are by default.
#
# No matter how automated this gets, you'll always need to read
# and re-read pumpkin.pod and release_managers_guide.pod to
# check for things to be done at various stages of the process.
