git_hooks/update_copyright.pre-commit:
Document the operation of this script in more detail.
Document the use of the new Makefile, and of the new environment
variable that can be used to avoid redundant copies of the update_copyright
program's executable.
git_hooks/Makefile:
Add a trivial makefile to shorten the build and clean commands.
git_hooks/update_copyright.m:
Merge contiguous year ranges in copyright lines.
git_hooks/update_copyright.m:
git_hooks/.gitignore:
Add the update_copyright program. It is deliberately not integrated
into the build system as it should be compiled once, manually, then
left in the workspace across checkouts, mmake clean, etc.
git_hooks/update_copyright.pre-commit:
Add a sample git pre-commit hook. It is up to the developer to
enable the hook in his/her workspace if desired.
