# Do not edit the manual page in this directory.  The manual is
# maintained as separate pages on the FreedomBox wiki and aggregated
# into a single page using the MoinMoin include feature.  Then it is
# exported as Docbook format and kept here.
#
# It is important to keep a copy of the manual in this source tree
# because Debian packages promise an entire source tree including the
# documentation.
#
# Use 'make fetch' to retrieve the latest manual from the wiki and
# commit it to the repository.  The wiki page is already reviewed, so
# commits that update the manual just using the 'fetch' target do not
# require further reviews.
