# 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.

# This is a bit convoluted to deal with the fact that make will overlap I/O from child make processes
# if they write more than 2k: this will corrupt the INDEX file.  make -P does not do this, but it adds
# extraneous output and redirects stderr, so we lose error reporting from child makes.  Instead we have
# to roll our own implementation of make -P and make sure that each child make writes to their own file,
# which we will combine at the end.  This gives substantial performance benefits over doing a make -j1
