# Compilation Options
# Debug mode [yes/no] (allowing to debug the library via gdb):
DEBUG ?= no
# Specify your favourite C compiler here:
COMPILE ?= gcc
# Specify your include directory (headers location):
INCDIR ?= /usr/include
# Specify your libraries directory:

# Specify location of man pages on your machine:
