## Why It Matters
SDF Toolkit provides a focused set of scripts for handling the Structure-data file format, a common format used to represent chemical structure records. By explicitly supporting both readable and writable operations for the Structure-data file, the toolkit serves as a practical utility for workflows that need to parse, generate, or manipulate SDF files. Its distribution by the National Cancer Institute and release under BSD licenses make it accessible for research and integration into other software projects. Having a dedicated SourceForge project and an official project page centralizes access to the toolkit's resources and documentation, which helps users locate and reuse the scripts in computational chemistry, cheminformatics, and data-processing pipelines that rely on SDF as an interchange format.
