### system dependant definitions, change when you install cxref

# for my use during development, put in my bin, but see next few lines.
DESTDIR= $(BIN)
LIB= $(BIN)

# when installing, use the lines below; change DESTDIR to local bin of choice.
DESTDIR=/usr/local/bin
LIB=/usr/local/lib/cxref
MANDIR=/usr/local/man

# where to put the man page, use 1 instead of l if you don't have a manl.
MANSEC=l

# lex library, may be -lln on some systems
LEXLIB= -ll

# may be /bin/sort on some systems
SORT=/usr/bin/sort

# printer program, prt is for me, use pr on other systems
P=pr

# the owner and group of the installed program.  Both are 'admin' on our
# system, but they may different on yours.
