+Sgrep (sorted grep) searches sorted input files for lines that match a
+search key and outputs the matching lines. When searching large files
+sgrep is much faster than traditional Unix grep, but with significant
+restrictions.
+
+ * All input files must be sorted regular files.
+ * The sort key must start at the beginning of the line.
+ * The search key matches only at the beginning of the line.
+ * No regular expression support.

+# 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.
