Archive-name: xbv/patch3
Patch-To: xbv: Volume 6, Issue 37,40
The following patch to xbv cleans up a few bugs, and, thanks to Jim Wight of
the University of Newcastle upon Tyne, changes things so that xbv can read a
bitmap from stdin.

the use of the \fIxsetroot\fR(1) command. This program is written entirely

+ .I bitmapfile
+ Specifies the name of a X11 bitmap file to read. If a filename is not specified,

+ Newcastle upon Tyne, UK.)
.SH NOTES
.I Xbv
is one of the few ways to easily display an X bitmap without resorting to
the use of the \fIxsetroot\fR(1) command. This program is written entirely
