File cap2.tgz was produced with the command -

	cd; tar czf /tmp/cap2.tgz cap2

To extract the files in this tarball, change to the directory you want
cap2 to be a subdirectory of, and enter -

	tar xzf /tmp/cap2.tgz

The tarball contains an executable binary for the CAPLIB2 APL
interpreter, cap2/bin/apl2, and an archive, cap2/lib/libcap2.a, with all
the object files for the CAPLIB2 subroutines.  However, if you'd like to
recreate the executable binary and archive from the original source,
change to the cap2 subdirectory, and do these commands:

	rm makefile; make

NOTE:  Don't make the mistake of doing "rm Makefile; make."  The
Makefile in this directory contains instructions for building makefile,
then recursively calling make.

For a brief introduction to the CAPLIB2 APL2 interpreter, see the
READ.ME file.
