Design

Components:

• wrappers around posix i/o to handle common, non-fatal errors (e.g., EINTR)
• component to manipulate paths (e.g., basename, dirname, transform /a/b/../c// into /a/c)
• abstraction for stat data structure
• API to read / write stat data structures to files
• API to filter and sort stat data structures
• parallel directory walk

Tools:

• list
• find
• copy
• remove
• tar/zip
• grep
• compare
