cpm looks nice indeed but will cpm run on windows and macos?
keepass probably integrates better with GUI's thanks to its drag&drop and autotyping of passwords into forms.
It has a wide array of features and is constantly getting new ones.
The documentation is excellent and it is translated into many languages.
It can export its database into many formats (xml, csv, html, arbitrary xsl transformations, ...).
It has many plugins including one for command line scripting (although I have not yet tested it on debian).
Upstream is very active and supportive. There are regular releases with bugfixes and features since more than 6 years.
Also keepass is very widely used, it is currently top 30 most downloaded of last month, top 70 all time on sourceforge.
I think all these points warrant a little duplicate functionality in the archive.
