NAME
enfle - Plugin-based Graphic loader

SYNOPSIS
enfle [options] files ...

DESCRIPTION
Enfle aims to view many variously formated pictures easily. So far, it can treat GIF, JPEG, PNG, MAG, BMP(partial), XPM(partial), PNM, DjVu, and several special (minor) formats. It has been implemented plugin mechanism so that each user can choose each format support linked in main program or separated as plugin. Moreover, you can make you own plugins to extend supported formats. However, GIF plugin is not included by default because of patent probrem. DjVu plugin is not included by default because standard libdjvu++ distribution doesn't create shared library (I've patched for myself) and I don't understand its license enough. Enfle needs the following library.
 JPEG: jpegsrc-6b (libjpeg)
 PNG: libpng-1.0.2 or later (recommend: 1.0.5)
 gz: zlib-1.1.3
 bz2: bzip2-0.9.5d
 libarc: libarc-1.4.9 (http://www.goice.co.jp/member/mo/release/)
