### definitions of files to compile and load, and other targets for make

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

# 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
