sample.library.  It also includes some example code that uses the library.
The files include:

 makefile            a make file to build the library and examples.
 asmsupp.i           assorted low level assembly support routines used by
                     the example library.
 sample_rev.i        the version file generated by bumprev.
 sample_protos.h     prototypes for sample.library functions.
 sample_pragmas.h    pragmas for sample.library functions.
 samplebase.i        definition of sample.library base.
 samplebase.h        include file defining sample.library base.
 sample.library.asm  example run-time library source code.
 sample_lvos.asm     the .fd file for the sample library.
 sample_stubs.asm    assembler stubs for c interface to library functions.
 clibtest.c          c example that calls the sample.library functions.
 alibtest.asm        assembly code example that calls the sample.library
                     functions.
