sbbdep takes a snapshot of installed packages, extracts information about binary runtime dependencies and stores it in a sqlite3 database which is kept in sync.
On its first run sbbdep indexes all installed packages, scans for binary and
library files, and stores the found information in a cache.
The cache file location can be specified with the -c or --cache option;
the default is $HOME/.cache/sbbdep.db.
The cache file must be readable and writable.
Each time sbbdep is executed it scans the system for changes.
If changes are found the cache is updated.
This is normally very fast, but when changes are found there is an additional
constant-time step where sbbdep resolves symbolic links in the file system.
Synchronisation can be skipped with --nosync, however, if packages have been
installed or removed since the last sync the query results may be stale.
During synchronisation sbbdep reports its activity to standard output.
This can be suppressed with the --quiet option.
Since the dependency info is stored in a sqlite3 database it can be accessed
directly with any sqlite3 client.
The schema is documented in README_db.txt in the source tree.
