Quick hacked makefile for Phobos on FreeBSD

my-freebsd.mak

# Makefile to build FreeBSD D runtime library libphobos2.a and its unit test
#
# make clean => removes all targets built by the makefile
#
# make zip => creates a zip file of all the sources (not targets)
# referred to by the makefile, including the makefile
#
# make release => makes release build of the library (this is also the
# default target)
#
# make debug => makes debug build of the library
#
# make unittest => builds all unittests (for both debug and release)
# and runs them
#
# make html => makes html documentation
#
# make install => copies library to /usr/lib 

# Configurable stuff, usually from the command line
#
