admin/maketx and src/Makefile might have unnecessary dynamic loading switches
thrown in.  Check whether or not -rdynamic is really needed.
done:  2003-04-19 alnd
-rdynamic was not needed in either admin/maketx or Makefile.linux (src/Makefile
never had -rdynamic in the first place)

tester/op4 needs test that creates sparse matrices then converts them to dense
before load/save.  This helps exercise the dense op4 features for skipping
null columns and skipping leading and trailing zeros within a column.

Need words that can assemble sparse matrices from sparse and dense sub-matrices 
and row/col vectors.

Implement sparse x sparse matrix multiplication.

Add interface to Metis (sparse matrix partitioning).

entry: 2003-04-10 alnd
Add interface to SuperLU (sparse matrix LU decomposition, solution).

entry: 2003-04-10 alnd
Add interface to ARPACK (sparse matrix eigensolution).

Get dynamic loading of .tx files to work on AIX.

Add interface to sqlite (database functions).

Add 'install' target to top level makefile.  It would copy the tops executable,
sys/ and usr/ directories to the location defined by 'configure --prefix=XXX'.

entry: 2003-04-12 alnd
Use autoconf to generate configure script.  (see autoconf manual at
http://www.gnu.org/manual/autoconf/html_node/autoconf.html#SEC_Top)

scanop4/loadop4 broken on Sun (words return immediately with "file error")
Consider replacing slice scheme with an op4 library and writing separate API
routines for tops, matlab, octave.

entry: 2003-04-12 alnd
Document sparse matrix data structure, sparse matrix creation and access array
binding routines.

entry: 2003-04-12 alnd
Add out-of-core option to matstk and volstk:  rather than returning with the
MEMNOT error they should associate a file name with the stack item and flag the
stack item as being stored on disk.

entry: 2003-04-12 alnd
Add a word similar to matlab's "who" and "whos" commands that show all user-named
variables (those beyond the end of the start-up fence), their types, and their sizes.
