# Makefile for the Scala compiler. Needs GNU Make.
# $Id$

# Main targets:
#   all (default)
#     Recompile every file that was modified after the latest
#     compilation ended. The date of the latest compilation end is
#     remembered through the files .latest-(compiler|runtime).
#   util
#     Recompile only utility files, used by the compiler.
#   compiler
#     Recompile only files which belong to the compiler.
#   runtime
#     Recompile only files which belong to the run-time.
#   regtest
#     Perform regression testing.
#   force
#     Recompile everything, no matter when source files were modified.
#   clean
#     Remove everything in the $(PROJECT_GENDIR)/scala directory.

# There are also targets to run grep on all files and to count the
# number of lines.

# Directory in which .class files should be put.
# BEWARE! The whole contents of the "scala" subdirectory in this
# directory is wiped out by a "make clean" so don't put anything else
# than automatically-generated .class files there.
