** Usage: zipdir <zip file> <directory> ...
|
|
**
|
|
** Given one or more directories, their contents are scanned recursively.
|
|
** If any files are newer than the zip file or the zip file does not exist,
|
|
** then everything in the specified directories is stored in the zip. The
|
|
** base directory names are not stored in the zip file, but subdirectories
|
|
** recursed into are stored.
