* module/Makefile.am: Add language/sassy.scm. Probably EXTRA_DIST the dependant files, too. * module/language/sassy.scm: New file, the sassy loader. Sassy is originally R5RS code that loads a number of files. I've converted that toplevel file to be a Guile module that *includes* the subfiles, so that it all gets compiled together. It's a pretty bad hack though, because what I should be doing is including them relative to the sassy.scm source location, but we don't know that at expansion time. Something to fix. really bad hack in it so that it will compile correctly -- p * module/language/sassy/: All the sassy files and some changelog information. All of these files are LGPLv2.1+, so they can be included in Guile. * test-suite/standalone/sassy/tests/: Add the sassy unit tests. * test-suite/standalone/Makefile.am: * test-suite/standalone/test-sassy: Hook the sassy unit tests up to our test suite.
