/* expect.h - include file for using the expect library, libexpect.a
from C or C++ (i.e., without Tcl)
 
Written by: Don Libes, libes@cme.nist.gov, NIST, 12/3/90
 
Design and implementation of this program was paid for by U.S. tax
dollars.  Therefore it is public domain.  However, the author and NIST
would appreciate credit if this program or parts of it are used.
