Hi Grigore
IMHO, PDM does create really useful documentation that is simple create and keep up to date since it runs so quickly. I run it at least weekly on changing projects so that I always have current docs. The latest version of PDM is much improved, allows selection of the types of source files to document, has multiple formatting options and now includes report form documentation that is really extensive. If you would like to try the beta version, let me know.
