The latex-tools gem is a collection of classes that facilitate the writing of various elements of Latex code. It is not designed for authoring entire Latex files, merely their component parts. Right now, it only consists of one such 'tool', LatexTable, which provides an easy and convenient way of outputting Latex code for tables from data in a ruby script.
