# To install Calc for private use, type `make'.
# To install Calc for public use, type `make install'.

# How to read a Makefile:
#   The command `make target' looks for `target:' in the Makefile.
#   First, any sub-targets after the `:' are made.
#   Then, the Unix commands on the following lines are executed.
#   `$(SYMBOL)' expands according to the `SYMBOL =' definition below.
