+Libaec provides fast lossless compression of 1 up to 32 bit wide signed or
+unsigned integers (samples). The library achieves best results for low entropy
+data as often encountered in space imaging instrument data or numerical model
+output from weather or climate simulations. While floating point
+representations are not directly supported, they can also be efficiently coded
+by grouping exponents and mantissa.
+
+Libaec implements Golomb-Rice coding as defined in the Space Data System
+Standard documents [121.0-B-2][1] and [120.0-G-2][2].
+
+Libaec can replace SZIP.

+# 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.
