Roap is a text file processor. It scans a text file, extracts regions that match specified patterns, and processes these regions sequentially using specifed executables. Each executable reads the region as stdin, and their combined stdouts are written as the stdout of Roap. Patterns and executables are specified using XML.
mtail is a small tail workalike that performs output coloring using ANSI escape sequences (although the sequences are overridable, so you could cause it to output something else, e.g., HTML font tags). It is written in python, is fairly small, and should be relatively platform-independent.
Tkinter is Python's de facto standard GUI (Graphical User Interface) package. It is a thin object-oriented layer on top of Tcl/Tk. To use Tkinter, you don't need to write Tcl code, but you will need to consult the Tk documentation and occasionally the Tcl documentation (since Tk's low-level event handling mechanism is considered part of Tcl).
Actim allows you to send and retrieve files, and to call command line programs on a target machine via emails. The application can handle both synchronous and asynchronous requests with basic security features. It has both command line and graphical user interfaces. This can be useful if, for example, your home PC does not have any access to your office workstation which is behind the company firewall.
OpenEV is a library and reference application for viewing and analysing raster and vector geospatial data. OpenEV capabilities include the following: handling of raster and vector data, support for 2D and 3D display, graceful handling of very large (gigabyte) raster datasets, support for multi-channel raster datasets, understanding and interpreting of georeferencing information, pan/zoom/rotate at interactive frame rates (using OpenGL), and a powerful image analysis tool (using Numerical Python).
MapIt! is a simple Web-mapping application implemented in Python that lets you navigate raster maps through your Web browser. It lets you zoom in and out, and select objects and object classes that are highlighted on the map. MapIt! can be integrated with an existing Web server in several ways: as a CGI script, Fast-CGI, or in Apache with mod_python. It can also serve GIS results over the Web.
Berkeley DB is a programmatic toolkit that provides high-performance built-in database support for desktop and server applications. The Berkeley DB access methods include B+tree, Extended Linear Hashing, Fixed and Variable-length records, and Queues. Berkeley DB provides full transactional support, database recovery, online backups, multi- threaded and multi-process access, etc. The Python wrappers allow you to store Python string objects of any length, keyed either by strings or integers depending on the database access method. With the use of another module in the package standard shelve-like functionality is provided allowing you to store any picklable Python object!
