Announcement text given by the package's contributor:
The makedtx bundle is provided to help LaTeX2e developers to write the code and documentation in separate files, and then combine them into a single .dtx file for distribution. It automatically generates the character table, and also writes the associated installation (.ins) script.
i've installed the package in support/makedtx; it should make its way to the other ctan sites in the next few hours.
thanks for the upload.
