htgrep

	Status	: stable
	Download	: htgrep (5 KB)

This is a frontend to the well known grep tool, using HTML as output. You can first see the matches with a quick glance in the summary part, then jump to a specific context with a single clic, and finally reach the source file if it happens to be online somewhere.
