# Makefile for unalf, by B. Watson. WTFPL.
# Tested with GNU make, BSD make, makepp, and Schily's dmake.

### Override these variables as needed. Don't override CFLAGS; use

# C compiler to use. PATH is searched unless you give an absolute path.
CC=cc

# Path to the GNU or BSD 'install' program.
INSTALL=install

# Path to the rst2man command. Only needed if modifying/rebuilding the
