# dist-bin-release: Rebuild binaries with optimizations and no debug

#
# dist-bin-commit: Creates a new vXX.XX.XX-ARCH branch with the
#   binaries and pushes it to the remote called bin.
#
# dist-bin-commit-common: Creates a new vXX.XX.XX-common branch with
#   the architecture-independent parts of VLFeat.
#
# dist-bin-merge: Creates a new vXX.XX.XX-bin branch by merging the
#   architecture specific binary branches and adding additional
#   files. It then pushes the result to the remote called bin.
#
# dist-bin: Packs the commit remotes/bin/vXX.XX.XX-bin.
#
# dist-src: Packs the commit vXX.XX.XX.
