Dear CTAN/Robin,
I have uploaded expressg.tar.gz to UK incoming. Please use this to
replace the current graphics/metapost/contrib/macros/expressg. The distribution is under the LPPL.
From the README
The expressg MetaPost package provides facilities to assist in
drawing diagrams that consist of boxes, lines, and annotations, such as IDEF or UML. Particular support is provided for creating EXPRESS-G diagrams.
Changes v1.61 (2004/03/17) o Added parentheses to namespace macro.
i've installed the upload as requested -- thanks for the upload.
