## Description: Makefile to compile programs using the humlib library.
##
## To run this makefile, type (without quotes) "make -f Makefile.programs",
## (or "gmake -f Makefile.programs" on FreeBSD computers). However this makefile
## is intended to be used with the file "Makefile" which runs this makefile with
## the command "make programs".  The program executables will be placed
## in the "bin" directory.
##
## Without arguments or with the argument "all", this makefile will
## compile all programs.  If you give a program name as an argument, it
## will compile just that program. E.g.: "make -f Makefile.programs flipper"
## or used in conjunction with "Makefile", type "make flipper", which will
## compile the cli/flipper.cpp program and place it in the ./bin directory.
##

# Set the environmental variable $MACOSX_DEPLOYMENT_TARGET to
# "10.9" in Apple OS X to compile for OS X 10.9 and later.
