6 # To have git run this script on commit, first make sure you change
7 # BRANCH_OFFSET to 60000 or higher, then create a "pre-commit" text file in
8 # .git/hooks/ with the following content:
10 # if [ -x .private/pre-commit.sh ]; then
11 # source .private/pre-commit.sh
14 # NOTE: These versioning hooks are intended to be used *INTERNALLY* by the
15 # libusbx development team and are NOT intended to solve versioning for any
16 # derivative branch, such as one you would create for private development.
18 # Should you wish to reuse these scripts for your own versioning, in your own
19 # private branch, we kindly ask you to first set BRANCH_OFFSET to 60000, or
20 # higher, as any offset below below 60000 is *RESERVED* for libusbx official
