Karl Heinz Marbaise commented on MLATEX-12:
-------------------------------------------
I found out after diving into the source code of the plugin that it was
intended to convert a number of latex files instead of a single one which
couldn't be defined by docRoots...which must be a directory instead of a file.
This might be documented in a better way into the documentation of the plugin.
