sgrep (structured grep) is a tool for searching text files
and filtering text streams using structural criteria. The
data model of sgrep is based on regions, which are non-
empty substrings of text. Regions are typically occur-
rences of constant strings or meaningful text elements,
which are recognizable through some delimiting strings.
