j_lib2 -- Library for Useful Functions

Objects in this library goes back decades, some started out on MS-DOS and a little known Unix called IN/ix (a 16 bit Unix on a proprietary 8086 clone).

To build, execute gen_make.sh to generate a Makefile for most BSD/Linux systems and IBM AIX. makefile.dos can be used for MS-DOS Systems under Microsoft c.

GNU automake https://en.wikipedia.org/wiki/Automake only confuses me, so I came up with my own method which is a real hack. But works for me.
