+and binary files, source code, archives, compressed files, documents, and
+more.
+
+While still being compatible with the standard GNU/BSD grep command-line
+options, ugrep supports fuzzy search as well as structured and (adjustable)
+colored output, piped through \"less\" for pagination.  An interactive query
+UI allows refinement and has a built-in help (press F1).  Ugrep implements
+multi-threaded and other techniques to speed up search, pattern-matching and
+decompression.  Many pre-defined regexps ease searching e.g. C typdefs or XML
+attributes.  Results can be output in several structured or self-defined
+formats.")
