It verifies that all the files present in a source directory structure are +present in a destination directory structure. + +## Status +Very much half baked, but does what I need it to do + +## Safety +This tool uses a (filename, filesize) pair. So, will protect you if your file was +truncated for some reason, but not against file corruption due to dodgy SD card, cosmic +rays etc. Doing this rather than comparing contents or hashes allows us to run very +quickly over many files. + + +## Usage +`./photocheck path/to/source path/to/dest`
