# emk - everest make - clear and concise build system
# for Everest Linux - build script template

# Output should follow this general format:
# emk INFO | output here
# emk WARN | output here
# emk ERR  | output here

# Colored output should be impletemted where possible.
# In /etc/emk.conf, colors are defined by variable, ex:
# ${red} 	for errors
# ${yellow}	for warnings
# ${blue}	for general info
# ${reset}	for removing colors

# Define working directory and source directory
# WORKING_DIR should not be changed.
# SRC_DIR should be changed to a directory which contains all
# source files and subdirectories
WORKING_DIR=$(pwd)
SRC_DIR=$(pwd)/../src # from working dir, go back and go into src

# Parse a local file containing settings for the installation
