From the developer:
ACTerm is a color terminal emulator that provides access to the core Unix functions of MAC OS X. Each terminal window is defined by a ACTerm session file or ACTSH file. The default startup is an interactive shell: bash (Bourne-again shell). ACTSH files can be launched from the desktop or through Finder.
