The Modula-3 sources under this directory were obtained from several
source directories provided by Luis on several dates. 

The sub-directories with date-like names are the remnants of those
original directories, after several hours of unzipping and path
flattening (so that, e.g.
"~lplozada/programs/pm3/Several/src/Others/TestCorner.m3.gz" became
2003-03-28/progs/TestCorner.m3).

In this reoriganization, all of Luis's libraries were
merged into "{DATE}/lib" sub-directories, and all Modula-3 main
programs were put into "{DATE}/progs".  Stolfi's minimization library
files were left separate, as "{DATE}/libm3nmin" directories.
Some files were renamed, e.g. "{DATE}/OptShape/OptShape-Old.m3"
became "{EARLIERDATE}/progs/OptShape.m3".  Shell scripts 
were put in "{DATE}/scripts". (However, most scripts were in the 
working directories, which were moved to ~/projects/toposcope-3d
and reorganized by different principles).

After that reorganization, the most recent version of each source file
was copied to "latest/{lib,progs,scripts}". Beware that this selection
was based on mod-time dates, and may have resulted in obsolete
versions (or new buggy versions) being selected over the correct ones.
It may also have introduced library-program incompatibilities. The
"latest" set probably includes many obsolete files that were abandoned
or renamed by Luis during his work.
