I use Make extensively for glue scripts or build scripts that call other tools. Make gives you four big advantages over a pure shell-script:
1. Tab completion. All major bash-completion packages know how to show Makefile targets in response to a TAB.
2. Parallel, serial, or single-target execution.
3. Automatic dependency resolution between tasks. Tasks that build files can also use timestamps to see what needs rebuilding.
4. Discoverability. Anybody who sees a Makefile will usually understand that something is supposed to be run from the Makefile's directory. Chances are good that they'll check the tab-completions too. There are conventions for standard targets like 'clean' and 'all'.
If you have a project with a build-process that has a bunch of small tasks that you might sometimes want to run piece-by-piece, Make is the perfect tool IMO.
