The '''TDE Accessibility''' software aims to provide means for all users, even those with physical handicaps, to use the '''Trinity Desktop Environment''' and the many applications it includes. Several helpful programs are included in the package:

As previously mentioned tdeaccessibility replaces a KDE3 package providing the same functionality. '''A build script based on release 3.5.X of kdeadccessibility exists''' and can be used as a template. The build system has not been ported to '''[http://www.cmake.org cmake]''' yet and still relies on '''autotools'''. Particular care should be put in configuring the source code including, were needs be, some hints from the deprecated TDE build kit for Slackware. The build phase should not require for large updates to the script.

Accordingly to the project guidelines '''/opt/trinity''' was configured as root directory for the package. The source code extracted from the archive lacks some configuration files needed by the build procedure. The missing files were created recurring to command '''make'''. Last '''a patch was applied''' to '''solve a libtool inconsistency''' between the source code expected version, 2.2.6, and the installed one: 2.4.2. Some script lines of code and related comments follow.

Finally the script runs the '''./configure''' command with the proper option list. Among them a special mention goes to '''--enable-closure''' and the '''--enable-kttsd-*''' options required by the speech synthesizer:

Once the configuration successfully concludes, the script runs the make command then goes on with packaging the software.
