No longer strips the main Python executable, as that was breaking the ability
of dlopen() and thus import .so based modules.
This change depends on changes to keg & formula that allow files to not be
cleaned.
Also, replaced a duplicate libpython2.6.a with a link (saves 6MB.)
Large refactor to Formula, mostly improving reliability and error handling but
also layout and readability.
General improvements so testing can be more complete.
Patches are automatically downloaded and applied for Formula that return a
list of urls from Formula::patches.
Split out the brew command logic to facilitate testing.
Facility from Adam Vandenberg to allow selective cleaning of files, added
because Python doesn't work when stripped.
Also removed xmlrpc-c dep, by coercing cmake into using its own xmlrpc
copy. It statically linked xmlrpc before anyway, so it's better for our
users not to have this crappy dependency.
Still completely in the dark about how cmake can possibly need an
xmlrpc library!
strip unlinks the file first, breaking hard links, so we detect instances where we are about to strip a file with many linkages and prevent it.
This fixes the libexec non executable bug in the git package.
Took me a long time to figure out what was wrong! :P
Moved Forumla and Cellar/homebrew into Library.
This way the homebrew core files are more sensibly placed, Cellar is
more internally consistent and only generated. And Homebrew is ready for
use straight out of the tarball.
