Sgraph is GraphEd's programming library.

For standalone Sgraph applications, take the files

algorithms.h
application_interface.h
sedge.c
sgragra_interface.h
sgraph.c
sgraph.h
sgraph_interface.h
slist.c
slist.h
snode.c
std.c
std.h
sscanner.l
sparser.y

and #define SGRAPH_STANDALONE in std.h.

This should do; remember that sscanner.l and sparser.y need lex and yacc.
