Provides a simple series of tools to allow single-file version control offering a number of features: Binary file handling - the tool makes use of a binary file differencing algorithm meaning it can handle both text and binary file contents effectively. Space efficiency - only differences are stored, not whole versions. This does impact extraction performance (especially for older versions), but ensures a minimum amount of disk space is used. Compression support - the impact of keeping multiple versions of a file is further reduced by making use of compression. Simplicity - the file format does not support branching or merging - just a linear series of changes. Tags - versions can be assigned an arbitrary number of tags and versions can be matched using a simple numeric version, the SHA1 checksum of the version or one of the tags.
