1.1 misho 1: #!/bin/sh -e
2:
3: # This script will setup the build dir based on the current git branch and the
4: # directory auto-build-save/$BRANCH. We don't use a symlink for the build dir
5: # because we want to maximize the ccache reuse, so all builds must happen in
6: # the same real dir. When a dir is moved out of auto-build-save/$BRANCH to the
7: # build dir, it is replaced with a symlink so that it can still be found under
8: # that dir. The build dir also gets a .branch -> $BRANCH symlink so that we
9: # can figure out the current build dir's branch.
10:
11: # To get started, just clone the rsync git repo and create the auto-build-save
12: # dir. If you have an existing git checkout and it is not in a pristine state,
13: # run "make distclean" before creating the auto-build-save dir.
