SIR: a simple indexing and retrieval system for biological flat file databases.

SUMMARY: SIR is a Simple Indexing and Retrieval tool for indexing and searching biological flat file databases. SIR is a cross-platform solution entirely written in Python. Since the package is very small and installation is trivial, this would be an ideal solution for database providers to provide a custom retrieval tool to access them. AVAILABILITY: The modules will be made available at http://www.EMBLHeidelberg.de/~chenna/PySAT/sir.html
