** COMMAND: deconstruct*

**
**
** This command exports all artifacts of a given repository and

** AABBBBBBBBB.. is the 40 character artifact ID, AA the first 2 characters.
** If -L|--prefixlength is given, the length (default 2) of the directory
** prefix can be set to 0,1,..,9 characters.
** 
** Options:
**   -R|--repository REPOSITORY  deconstruct given REPOSITORY
**   -L|--prefixlength N         set the length of the names of the DESTINATION
**                               subdirectories to N
**   --private                   Include private artifacts.
