"browser" computes the interface of all Sather classes used in a program.
Based on the Sather compiler (tiny modification).

Make sure "Compiler" points to the Sather compiler source code.

usage:
	$ browser arguments >features.txt
	  (arguments are same as those for the Sather compiler)
	  class interfaces reported on stdout.
	$ cat >classes.txt
        class = INT
        class = FLTD
        ...
        ^D
	$ cat >omit.txt
	FLT::bessel_yn(INT):FLT
	FLT::bessel_jn(INT):FLT
	FLT::sinpi:FLT
	...
	^D
        $ gawk -f graph.awk classes.txt features.txt >interface.sig
	$
