#   from: @(#)bsd.subdir.mk 5.9 (Berkeley) 2/1/91
# $FreeBSD$
#
# The include file <bsd.port.subdir.mk> contains the default targets
# for building ports subdirectories. 
#
#
# +++ variables +++
#
# STRIP     The flag passed to the install program to cause the binary
#       to be stripped.  This is to be used when building your
#       own install script so that the entire system can be made
#       stripped/not-stripped using a single knob. [-s]
#
# ECHO_MSG  Used to print all the '===>' style prompts - override this
#       to turn them off [echo].
#
# OPSYS     Get the operating system type [`uname -s`]
#
# SUBDIR    A list of subdirectories that should be built as well.
#       Each of the targets will execute the same target in the
#       subdirectories.
#
#
# +++ targets +++
#
#   README.html:
#       Creating README.html for package.
