The Man Pages editOnline versions of the man pages for Tcl and Tk can be found at:
Other ways to read the man pagesAmong the ways to access "the manual pages" are
- conventional Unix installations ... man ... see also tkman
- conventional Windows installation ... (see http://groups.yahoo.com/group/tcldocs/files/ for a download of .chm files for Windows which include more than just Tcl/Tk)
- neat JCW-authored scripted documents at 
Foreign Language TranslationsTranslated manual pages
Other documentation considerations editWhen writing documentation, a developer has to decide in what form to provide the documentation. There are various tools available to assist in this.There are Tcl specific tools, such as dtp/doctools software, which provides the ability to write doc in a general form, then to generate various file formats for display purposes. TMML and dtp are two tools designed to help Tcl developers document Tcl extensions and applications. Others can found at the Source Documentation Tools page.There is a tool called txt2man (see http://freshmeat.net/projects/txt2man/) which is said to convert plain ASCII text into man page format.
Fabricio Rocha - 05 May 2011 - I wonder if we Tclers could develop (or use) a tool for converting/filtering HTML to man, something that is surely possible. I ask this because once I read DKF explaining that the online versions of the man pages are so simple and ugly because they have to be in the "minimal denominator" format for allowing easier updates for both online versions and the man pages themselves. IMHO, this is a too severe limitation, specially for the Tk pages, which is not really needed. Mark Roseman created a beautiful, colorful TkDocs website with illustrations that, in my opinion, might and should be part of the online manual pages, so they would be much more friendly and clear to new Tclers. Of course man has its fans and is pretty useful when you're offline, but it does not need to dictate the formatting of pages in a multimedia web...
