# This Makefile is for Dropbear SSH Server and Client

# invocation:
# make PROGRAMS="dropbear dbclient scp" MULTI=1 STATIC=1 SCPPROGRESS=1
#
# to make a single multiple statically linked binary "staticdropbearmulti",
# which includes dropbear, scp and dbclient functionality, and includes the
# progress-bar functionality in scp. Hopefully that seems intuitive.

# This makefile is quite evil.
