2.1 Changes

• major cleanup and stability work to get a solid base out of the ROCK code base
• removal of custmain in glibc, binutils, gcc, xorg and many other packages
• many packages got split (alsa, mad, ogg-vorbis, xine, ...)
• distcc support
• revisited ccache support
• revisited fl_wrapper and parsing (including major performance improvements)
• bi-arch 32/64bit support (useful on x86-64, sparc64, powerpc64, ...)
• x86-64 support
• enhanced sparc64 support
• revisited cross compile support
• enhanced uclibc / dietlibc support
• embedded target
• revisited build-time dependency computation
• revisited Emerge-Pkg (huge usability enhancements)
• stricter checking of top-level dirs created by the package
• post install instead of cron.daily ,-)
• pkgprefix and match_source_file helpers
• build package inside a package support to build all the third party modules for any kernel (postlinux)
• support to download all the extending packages of a packages automatically
• revisited cvs:// url scheme used in the .desc files, including svn:// and svn+http:// support
• added support to mark manual and non distributable downloads as well as not to be distributed packages
• target helper functions
• revisited .cache layout
• revisited source checksumming so no manual -r* is needed and packages are less often rebuild

Stuff especially ugly and thus obsoleted and removed stuff from the ROCK code base:

• only one gcc version included
• only X.org included
• only one (sanitized) linux-header package included
• no NODIST hack - but real support for fine grained download and distribution control (see changes above)
• no repositories named by peopl
• no package fork / split "crap" and no cpan meta package wanna
• no pseudo cross native "crap"
• no default kernel concept - instead way improved sanitzed linux-header and module build for any kernel
• no linux*-src packages - third party modules are build for any kernel (see above)
