GNATS was designed as a tool for software maintainers. It
consists of several utilities which, when used in concert,
formulate and administer a database of Problem Reports
grouped by site-defined "problem categories".
It allows a support organization to keep track of problems
(hence the term "Problem Report") in an organized fashion.
Essentially, GNATS acts as an active archive for
field-separated textual data submitted through electronic
mail.
