The Makefile copied from the old libs dir is broken by the new directory structure.
It does basically three things:
- run the tests
- run the benchmark
- rebuild data array files
(and fetch the unicode data files for the above)
- and 2) can be easily replaced with 'composer test' etc with appropriate config?
- can be replaced with a nice PHP script that fetches the files and runs the build scripts, which would be less shell-dependent and may work better for third-party users.
(IIRC the makefile was a little fragile and sometimes had to be tweaked to run on both OSX and Linux etc)
