This change eliminates O(2^N)-1 passes through the individual documents, where N is the number of levels of directory hierarchy. For a "make install" from the top level of the doc/ tree, files corresponding to individual documents were being installed eight (!!!) times. Reviewed by: trhodes, Szilveszter Adam

# This include file <doc.subdir.mk> contains the default targets
|
|
# for building subdirectories in the FreeBSD Documentation Project.
|
|
#
|
|
# For all of the directories listed in the variable SUBDIR, the
|
|
# specified directory will be visited and the target made. There is
|
|
# also a default target which allows the command "make subdir" where
|
|
# subdir is any directory listed in the variable SUBDIR.

# ------------------------------------------------------------------------
|
|
#
|
|
# Document-specific variables:
|
|
#
|
|
# SUBDIR A list of subdirectories that should be
|
|
# built as well. Each of the targets will
|
|
# execute the same target in the
|
|
# subdirectories.
|
|
#
|
|
# COMPAT_SYMLINK Create a symlink named in this variable
|
|
# to this directory, when installed.
|
|
#
|
|
# ROOT_SYMLINKS Create symlinks to the named directories
|
|
# in the document root, if the current
|
|
# language is the primary language (the
|
|
# PRI_LANG variable).
|
|
#

# ------------------------------------------------------------------------
|
|
#
|
|
# Provided targets:
|
|
#
|
|
# install:
|
|
# package:
|
|
# Go down subdirectories and call these targets
|
|
# along the way, and then call the real target
|
|
# here.
|
|
#
|
|
# clean:
|
|
# Remove files created by the build process (using
|
|
# defaults specified by environment)
|
|
#
|
|
# cleandir:
|
|
# Remove the object directory, if any.
|
|
#
|
|
# cleanall:
|
|
# Remove all possible generated files (all predictable
|
|
# combinations of ${FORMAT} values)
