Repgor is a simple report generator. It is especially useful for reports that involve computations on trees.

Repgor uses SWI-Prolog's CLP(Q) library and can compute expressions that are hard or impossible to obtain with SQL. Repgor uses ODBC to connect to a database, and executes SQL queries embedded in XML-templates.
