Komet 0.6 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac application was originally developed by Mayur Pawashe. We recommend checking the downloaded files with any free antivirus. The program lies within Developer Tools, more precisely Webmaster Tools.
From the developer:
Komet is a Cocoa text editor designed for creating commit messages. Not being stuck in a save-and-close model, applying a commit takes only one action in Komet. It supports double newline insertion after the first line. The tool features Cocoa's spell checking and automatic correction. It comes with a text highlight warning if line becomes too long for subject and/or body.
You may want to check out more Mac applications, such as Url Extractor X, Boks or Navicat for Oracle, which might be related to Komet.
