Convert HTML pages to WML (WAP) or i-mode pages for Mobile - Html2Wml

Html2Wml converts HTML pages to WML decks, suitable for being viewed on a Wap device. The program can be launched from a shell to statically convert a set of pages, or as a CGI to convert a particular (potentially dynamic) HTML resource.

Although the result is not guarantied to be valid WML, it should be the case for most pages. Good HTML pages will most probably produce valid WML decks. To check and correct your pages, you can use W3C's software: the *HTML Validator*, available online at and *HTML Tidy*, written by Dave Raggett.

Html2Wml provides the following features:
 * translation of the links
 * limitation of the cards size by splitting the result into several cards
 * inclusion of files (similar to the SSI)
 * compilation of the result (using the WML Tools, see the section on "LINKS")
 * a debug mode to check the result using validation functions

UI Application for Alternatives Configuration - Galternatives

update-alternatives creates, removes, maintains and  displays  information  about  the symbolic links comprising the Debian/Ubuntu alternatives system.

It is possible for several programs  fulfilling  the  same  or  similar functions  to  be  installed  on a single system at the same time.  For example, many systems have several  text  editors  installed  at  once. This gives choice to the users of a system, allowing each to use a different editor, if desired, but makes it difficult for a program to make a  good  choice for an editor to invoke if the user has not specified a particular preference.

Debian's alternatives system aims to solve  this  problem. A  generic name in the filesystem is shared by all files providing interchangeable functionality. The alternatives system and  the  system  administrator together  determine  which  actual  file  is referenced by this generic name. 

For example, if the browsers like Chrome, Firefox and Opera are installed on the system, the alternatives system will cause the generic name /usr/bin/x-www-browser to refer to /usr/bin/google-chrome by  default.  The  system administrator  can  override  this and cause it to refer to /usr/bin/firefox instead, and the alternatives system will not alter this setting  until explicitly requested to do so.
