+# 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.

+zstd: zstd (real-time compression algorithm)
+zstd:
+zstd: Zstandard, or zstd for short, is a real-time compression algorithm
+zstd: providing high compression ratios. It offers a very wide range of
+zstd: compression/speed trade-off, while being backed by a very fast
+zstd: decoder. It also offers a special mode for small data, called
+zstd: dictionary compression, and can create dictionaries from any sample
+zstd: set.
