Fast File Validator 0.47
A program for verifying files against a checksum file and for creating such checksum files
FFV supports both SFV files (which use the CRC32 algorithm) and MD5 files. Actually, it can handle both types of checksum in the same file, although you don't normally see this, and I don't recommend creating such files.
FFV is fast, because it's written directly to the Win32 API to avoid unnecessary overhead and it uses a multi-threaded design, so it can calculate the CRC while reading the file. (Note: In my limited tests, it's about 40% faster under NT 4.0 than under Windows 98, reading the same files off the same hard drive.)

What's New in This Release:
- You can now specify a directory to verify on the command line (to check all .SFV and .MD5 files in that directory).
- The test suite no longer requires Inline::C; just Perl.
- The POSIX version can now be compiled even if your system’s limits.h doesn’t define PATH_MAX.
