Gespeaker is a GTK+ frontend for espeak. It allows you to play a text in many languages with settings for voice, pitch, volume, and speed. The text can also be recorded to a WAV file for future listening. Gespeaker supports the speech synthesizer MBROLA for a better speech experience.
g7ctrl is a daemon and a command shell that are used together with the Xtreme GM7 GPS tracker to help simplify its management and to make it possible to monitor alerts sent by the tracker. It is designed to run in the background and can be used to both receive location updates from a remote tracker and configure a tracker over USB. All received events are stored in a database and can be exported to GPX, KML, and CSV, with distances calculated. It can also execute action scripts upon receiving specific events or generate mail notifications. Extensive reference documentation (HTML and PDF) and Unix man pages are provided.
ShellCheck is a static analysis tool for shell scripts. Its goals are to point out and clarify typical beginner's syntax issues that causes a shell to give cryptic error messages, to point out and clarify typical intermediate level semantic problems that causes a shell to behave strangely and counter-intuitively, and to point out subtle caveats, corner cases, and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances.
