Recursively scan a directory subdirectories that do not start with `.*` and
capture `sha1` hash for files that are `> 0` in size and not hidden (i.e. don't start with `.*`)
"Bless" a directory, associated subdirectories and files become references for future scans.
db-ls-dirs List dirs in the database.
db-ls-files List files in the database.
drop-db Drop the database file, if it exists.
init-db Clear the existing data and create new tables.
bless-dir Recursively scan a directory and subdirs and add all files as 'blessed'.
