# Makefile base template
# 
# Version:
# - 1.0.0: add a version comment
# - 1.1.0: add help, sjar
# - 1.1.1: fix "jar" instead of ${JAR}

# Required parameters (the commented out ones are supposed to change per project):

#MAIN = path to main java source to compile
#MORE = path to supplementary needed resources not linked from MAIN
#NAME = name of project (used for jar output file)
#PREFIX = usually /usr/local (where to install the program)
#TEST = path to main test source to compile
#JAR_FLAGS += a list of things to pack, each usually prefixed with "-C bin/"
#SJAR_FLAGS += a list of things to pack, each usually prefixed with "-C src/", for *-sources.jar files
#TEST_PARAMS = any parameter to pass to the test runnable when "test-run"

JAVAC = javac
JAVAC_FLAGS += -encoding UTF-8 -d ./bin/ -cp ./src/
JAVA = java
JAVA_FLAGS += -cp ./bin/
JAR = jar
RJAR = java
RJAR_FLAGS += -jar
