# This command prints out the dependency patterns for all full (run-time)
# dependencies of the package.
#
# This is used in install.mk and metadata.mk.
#

# ${_DEPENDS_FILE} contains all the dependency information
# for the package.  The format of each line of the file is:
#
#	<depends_type>	<pattern>	<directory>
#
# Valid dependency types are "bootstrap", "build" and "full".
#
# ${_RDEPENDS_FILE} contains the resolved dependency information
# for the package.  For each line in ${_DEPENDS_FILE}
# a corresponding line of the following form exists:
#
#	<depends_type>	<pattern>	<pkg>
#
# "pkg" is the match for "pattern" used to fulfill the dependency.
