+imgcurses (smart character-based image viewer)
+
+imgcurses displays images in a console or terminal using color
+ASCII art.
+
+* Do you browse the internet using lynx?
+* Do you wish the world was only 8 colors?
+* Do you pity your peers with their pathetic desktop applications?
+
+imgcurses might just be for you...
+
+The limited color palette introduces some pretty bad limitations,
+but unlike alternatives imgcurses is fully interactive and employs
+smart techniques to get the most out of viewing - it doesn't just map
+pixel values to ASCII characters. Images are best viewed scaled up,
+from a distance, and with a blurred focus. The combination of modes
+highlights different image features and makes an overall understanding
+of the image much more plausible.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
