# The include file <bsd.pkg.subdir.mk> contains the default targets

# +++ variables +++
#
# STRIPFLAG	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]
#
# 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.
