Modifications to the upstream source: This package uses quilt to manage all modifications to the upstream source. Changes are stored in the source package as diffs in debian/patches and applied during the build. Refer to /usr/share/doc/quilt/README.source for details. Repackaged upstream source: The BOINC project does not distribute source code releases as tarballs, but they are tagged in the BOINC Subversion repository. Anonymous Subversion access is available at http://boinc.berkeley.edu/svn/. The branch for the BOINC source is trunk/boinc, tagged releases are in tags/. For more information see: http://boinc.berkeley.edu/trac/wiki/SourceCode To obtain the source from Subversion and package it as .orig.tar.gz the Debian BOINC Maintainers use a script called 'export-boinc' which is available in our pkg-boinc Subversion repository: http://svn.debian.org/wsvn/pkg-boinc/scripts/export-boinc?op=file For example, to obtain the .orig.tar.gz tarball for BOINC version 5.8.17 this script is invoked as: $ export-boinc -r 5.8.17
