**       Create a new binary patch in FILENAME that captures all uncommitted
**       changes in the check-out at DIRECTORY, or the current directory if
**       DIRECTORY is omitted.  If FILENAME is "-" then the binary patch
**       is written to standard output.

**
** > fossil patch apply [DIRECTORY] FILENAME

**                          changes in the current check-out.  Unsaved changes
**                          are reverted and permanently lost.
**           -n|--dry-run   Do nothing, but print what would have happened.
**           -v|--verbose   Extra output explaining what happens.
**
