+glrpt can decode images in real time as they are received from
+the satellite and display them incrementally as they form,
+slow-scan TV fashion.
+
+The images displayed in the glrpt window are scaled down by a factor
+specified in the ~/glrpt/glrptrc configuration file.
+The APID channel images stored in ~/glrpt/images/ are full sized and
+are saved either in the PGM (Portable Grey Map) format or JPEG format.
+A new JPEG compression code in glrpt allows both monochrome and color
+images to be saved as good quality jpeg files.
+Please note that the images/ directory can be a relative link to some
+other directory of user's choice.

+# 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.
