'pw(8)' is the utility to create, delete, and modify users. This tool has remained mostly untouched since its creation, but needed updating.

Lots of cleanup has been done:

• Deduplication of code
• Reduction of complexity by splitting into smaller functions
• Reuse of existing code in base:
  • 'sbuf(9)' for buffered string
  • 'stringlist(3)' for string arrays
  • 'gr_utils' (from libutil) instead of homemade group manipulation
  • 'strptime(3)' to parse time strings
• Added validation on most input options, fixing some serious bugs due to bad usage of 'atoi(3)'
• many regression tests added to test for regressions due to all of these changes

A new feature was added: 'pw -R rootdir /cmd/' which allows cross manipulation of users.
