This is the Android Scripting Environment from googlecode with support added to install and use a Tcl interpreter. You need to copy the zip files to the root of your sdcard and then install this .apk file and select the Intpreters menu item and on the interpreters page select the Add menu item. Choose Tcl from the list and it should install everything.
NOTE the Tcl support patch was incorporated into the ASE distribution so the zip files here should work fine with the stock distribution. These are also available from the ASE download site.
