# Makefile for rc.

# Please check the configuration parameters in config.h (and if you want
# to make sure, the definitions in proto.h) to make sure they are correct
# for your system.

# Uncomment this line if you have defined the NOEXECVE macro in config.h
#EXECVE=execve.o

# Define this macro if you wish to extend rc via locally-defined builtins.
# An interface is provided in addon.[ch]. Note that the author does not
# endorse any such extensions, rather hopes that this way rc will become
# useful to more people.

# You may substitute "bison -y" for yacc. (You want to choose the one that
# makes a smaller y.tab.c. Also see the README about Sun's yacc.)
