An updated version of vcs is available to download. Shame on me for the long wait since this has been pretty much completed for months.
The biggest change this time is the "blank frame avoidance" feature, with which (mostly) blank frames will not be captured, if possible, this is one of the cool features found in mtn and worth stealing
Also worth noting is the ability to load profiles automatically. E.g. adding "profiles=white,mosaic" to your ~/.vcs.conf file will use both profiles. A new profile ("compact") is added, and a list of installed profiles can be obtained with $ vcs --profile :list.
The manual page is finished too.
Of course you'll have to download and install the full package instead of just the script to get the profiles and man page installed.
Other minor additions are the identification of captures from FRAPS and of course the usual batch of fixes and scheduled changes. FreeBSD users, and hopefully Mac OS X too though I can't check, can again use the script too.
Finally, please read «Features to be removed from VCS» if you have any interest in VCS' future versions.
See the full changelog for more details.
