4 # Script to help out with syncing cpan distros.
7 # - Fetches the package list from CPAN. Finds the current version of
8 # the given package. [1]
9 # - Downloads the relevant tarball; unpacks the tarball;. [1]
10 # - Clean out the old directory (git clean -dfx)
11 # - Moves the old directory out of the way, moves the new directory in place.
12 # - Restores any .gitignore file.
13 # - Removes files from @IGNORE and EXCLUDED
14 # - git add any new files.
15 # - git rm any files that are gone.
16 # - Remove the +x bit on files in t/
17 # - Remove the +x bit on files that don't have in enabled in the current dir
18 # - Restore files mentioned in CUSTOMIZED
19 # - Adds new files to MANIFEST
20 # - Runs a "make" (assumes a configure has been run)
22 # - Runs tests for the package
23 # - Runs the porting tests
25 # [1] If the --tarball option is given, then CPAN is not consulted.
26 # --tarball should be the path to the tarball; the version is extracted
27 # from the filename -- but can be overwritten by the --version option.
29 # TODO: - Delete files from MANIFEST
30 # - Update Porting/Maintainers.pl
31 # - Optional, run a full test suite
32 # - Handle complicated FILES
34 # This is an initial version; no attempt has been made yet to make this
35 # portable. It shells out instead of trying to find a Perl solution.
36 # In particular, it assumes wget, git, tar, chmod, perl, make, and rm
39 # Usage: perl Porting/sync-with-cpan <module>
40 # where <module> is the name it appears in the %Modules hash
41 # of Porting/Maintainers.pl
