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.")
