#=== These rules are used for man pages. ===#


# Enables the rules:
#   install-man               Install all man page
#   install-man-untranslated  Install untranslated man page
#   install-man-locale        Install translated man page
# 
# This file is ignored unless _MAN_PAGE_SECTIONS
# is defined. _MAN_PAGE_SECTIONS should list all
# used man page sections. For all used sections
# there should also be a variable named
# _MAN_$(SECTION) that lists the suffixless
# basename of all man pages in that section.
# 
# The pathname of a man page should look
# like this: doc/man/$(DOCUMENT).$(SECTION)
# Translations looks like this:
# doc/man/$(DOCUMENT).$(LANGUAGE).$(SECTION)
# 
# For each language and section, there should
# be a variable _MAN_$(LANGUAGE)_$(SECTION)
# that lists all translated documents in that
# section and for that lanuage. These should
# be suffixless basenames. The lanuage counts
# as a suffix.
# 
# The translations of the man pages to
# install should be specified, by language,
# in the variable MAN_LOCALES.
