ChordDB is a Web-based database front-end for keeping track of and typesetting chord files (a.k.a. guitar fake sheets). It accepts chord and chordpro files as inputs, and creates output sets in a large variety of formats (PDF, text, chordpro, LaTeX) with the help of pdftex and the LaTeX Songbook style. Songs are stored internally using SQLite, so there is very little need for configuration.
TeXToWebPublishing is a Perl script that produces a set of HTML pages from a LaTeX source file. The script creates one image for each HTML page. Each page in your slide presentation corresponds to one of the Postscript pages you would obtain running LaTeX. TeXToWebPublishing also produces an index page corresponding to the table of contents you would obtain with LaTeX. Each item of the index page includes a link to the corresponding HTML page. Links into the HTML pages can also be created with a special LaTeX command.
LaTeX is a document preparation system for high-quality typesetting based on TeX. It is most often used for medium-to-large technical or scientific documents, but it can be used for almost any form of publishing. It is not a word processor; instead, it encourages authors not to worry too much about the appearance of their documents, but to concentrate on getting the right content.
LaTeX Indexbuilder is a tool for build indexes in LaTeX. It looks inside a LaTeX document for a given list of words and adds the necessary LaTeX stuff to build a clean index. It does not handle the output made from \index calls by LaTeX, but takes care that every word in a list is correctly identified with the \index command without you doing the boring job by hand.
Bibgrep indexes and efficiently searches BibTex files. Its usage is similar to the command grep and the queries use a Google-like syntax. Bibgrep will create an index for each BibTex file it touches, and keep the result within "~/.bibgrep.idx" (by defaults). It watches the modification date and the size of the original BibTex file, and will update (and delete) its index as needed.
