6 # A tool to build a perl release tarball
7 # Very basic but functional - if you're on a unix system.
9 # If you're on Win32 then it should still work, but various Unix command-line
10 # tools will need to be available somewhere. An obvious choice is to install
11 # Cygwin and ensure its 'bin' folder is on the PATH in the shell where you run
12 # this script. The Cygwin 'bin' folder needs to precede the Windows 'system32'
13 # folder so that Cygwin's 'find' command is found in preference to the Windows
14 # 'find' command. In addition to the commands installed by default, your Cygwin
15 # installation will need to contain at least the 'cpio' and '7z' commands.
16 # Finally, ensure that the 'awk' and '7z' commands
17 # are copies of 'gawk.exe' and 'lib\p7zip\7z.exe' respectively,
18 # rather than the links to them that only work in a Cygwin bash shell which
19 # they are by default.
21 # No matter how automated this gets, you'll always need to read
22 # and re-read pumpkin.pod and release_managers_guide.pod to
23 # check for things to be done at various stages of the process.
