Hello John,

for now, the xls* func works in conjunction with a number of Java
packages, namely the Apache POI set. This introduces two dependencies,
one on the POI jar files which must be referenced in the JAVA class
path; the other is on Java itself. I spent some time recently to try
to get Java running under Octave in a cygwin environment without

If you want to integrate the xls* funcs into octave-core, this requires
1) to distribute and integrate the Apache POI libs;
2) to conditionnaly include this feature: a working Java
implementation must be available.

There's also another interface that uses COM from the Windows package, and uses Excel directly to read/write XLS files. Philip is probably the best one to list the various interfaces that can be used by the xls* functions.
