2. The Goal
• From any module file, report
• distro it came in
• dependencies at release time
• MiniCPAN for the installation
• Distributable database of all info
3. • Perl doesn't have a package manager
• No file-to-distro reverse mapping
• No version management
• Most people aren't up-to-date
• Most people shouldn't be up-to-date
4. • BackPAN is the bone yard of CPAN
• It has an evolutionary record
• No one explores it
• CPAN tools only care about now
5. Info to record
• File list, with meta-data
• What's in blib after `make`
• Packages in .pm files
• Modules used in .pm, .pl, .t files
• Prerequisites
