Description: upstream -- libtoolization -- version script support
 Provides version scripts [1] for the shipped libraries. The map
 (or version scripts) are basically generated from the package headers
 (themselves extracted from the TeX sources) with the help of cproto(1)
 (resp. with the provided tool tdoc). The version scripts are generated
 on the fly thought the [auto]make machinery (in maintainer-mode).
 Meant to be submitted to the upstream maintainer team.
