Doug Barton 2fadfa2cfb For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

fv is an HDRI viewer. Currently supported formats are the followings:
* Greg Ward's HDR (also known as Radiance/PIC/RGBE). See
http://www.graphics.cornell.edu/~bjw/rgbe.html for details.
* Paul Debevec's PFM (Portable Float Map). See
http://netpbm.sourceforge.net/doc/pfm.html for details.
fv reads data from the standard input or files specified as
arguments. In the latter case, each file may be compressed one with
gzip or bzip2. The file may also change after fv is invoked, except
its header part. fv checks whether the file changes and updates the
display if necessary. This feature is useful for checking intermediate
outputs from renderers.
