132	=head1 SYNOPSIS	152	=head1 SYNOPSIS
133		153
134	cv [file...]	154	cv [file...]
135		155
		156	=head1 FEATURES
		157
		158	CV is supposed to work similar to the venerable XV image viewer, just
		159	faster. Why faster?
		160
		161	=over 4
		162
		163	=item * optimized directory scanning algorithm
		164
		165	The directory scanning in CV plays some tricks that - on most modern
		166	filesystems - makes it possible to detect filetypes faster than stat()'ing
		167	every file. This makes CV suitable for directories with lots of files
		168	(10000+).
		169
		170	This algorithm is quite unprecise - it doesn't make a difference between
		171	files, device nodes, symlinks and the like, and filetype detection is done
		172	using the file extension only.
		173
		174	=item * use of asynchronous I/O
		175
		176	CV tries to use asynchronous I/O whereever it makes sense, for example
		177	while scanning directories, waiting for stat data or unlinking files. This
		178	usually decreases scanning times for large directories a bit (especially
		179	on RAID devices and over NFS).
		180
		181	=item * fast image loading
		182
		183	The time span between the user issuing a command and displaying the new
		184	image should be as small as possible. CV uses optimized (especially
		185	for JPEG) loading functions and sacrifices some quality (e.g no gamma
		186	correction) to achieve this speed.
		187
		188	=item * fast thumbnail creation
		189
		190	Thumbnail creation is crucial for me, so it's better be fast. Thumbnail
		191	creation for JPEGs has been specially optimized.
		192
		193	=item * minimum optical clutter
		194
		195	CV has no menus or other user interface elements that take up a lot of
		196	screen space. The schnauzer windows can also be somewhat crowded.
		197
		198	The point of an image viewer is viewing images, not a nice GUI. This is
		199	similar to XV's behaviour.
		200
		201	=item * efficient (and hard to learn) user interface
		202
		203	CV uses key combinations. A lot. If you are an experienced XV user, you
		204	will find most of these keys familiar. If not, CV might be hard to use at
		205	first, but will be an efficient tool later.
		206
		207	=item * i18n'ed filename handling throughout
		208
		209	As long as glib can recognize your filename encoding (either UTF-8 or
		210	locale-specific, depending on your settings) and you have the relevant
		211	fonts, CV will display your filenames correctly.
		212
		213	=item * extensible through plug-ins
		214
		215	I have weird plug-ins that access remote databases to find a
		216	directory. This is not likely to be of any use to other people. Likewise,
		217	others might have weird requirements I cannot dream of.
		218
		219	=item * filename clustering
		220
		221	Among the standard plug-ins is a filename clustering plug-in, that (in
		222	case of tens of thousands images in one directory) might be able to
		223	cluster similar names together.

		305	When starting, CV runs the F<.cvrc> file in your F<$HOME> directory as if

		308	Example:
		309
		310	system "fping -q -t 10 ether"
		311	or require "/fs/cv/cvplugin.pl";
		312
		313	This will load a plug-in, but only if the machine I<ether> is reachable
		314	(supposedly the plug-in is networked in some way :).
