+Tony Hansen (AT&T) wrote the first \fBinfocmp\fP in early 1984,

+Eric Raymond used the AT&T documentation in 1995 to provide an equivalent

+In addition, he added a few new features such as:

+the \fB\-e\fP option, to support \fIfallback\fP
+(compiled-in) terminal descriptions
+.bP
+the \fB\-i\fP option, to help with analysis
