# Support package. Handling of message catalogs within the various
# doctools document processing packages. Contrary to the regular
# msgcat package here message catalogs are equated with packages. This
# makes their use easier, as the user does not have to know the
# location of the message catalogs. Locating a desired catalog is
# handled through Tcl's regular package management.

# To this end this package provides a command analogous to
# 'msgcat::load', just replacing direct file access with package
# loading. This is 'doctools::msgcat::init'.
