clean-ups

• use Bos, Fpath, and other libraries for file operations
  • Expand tilde: Change OS.Dir.user and add OS.Dir.expand_tilde dbuenzli/bos#96
  • alternative implementation
• use json-data-encoding to handle JSON
• don’t resolve symbolic links unless necessary. Exceptions:
  • the current working directory

features

• Access to units within the same library
• Access to built-in libraries that are installed along with OPAM
• Locally redirection or vendoring of arbitrary dependencies
• Allow different branches of the same remote git repository (though not at the same time)
• Support of a public index from the web
• Support of a public index from a file
• Support of a public index from files installed along with OPAM
• Local building environments by default, and co-development of two or more local libraries as an option (e.g., changing both Yuujinchou and algaett at the same time)
• Options to work offline (which would turn off git auto-fetch)
• Thread/domain-safety

features for consideration

• Quick checking of dependencies
• Version constraint solving
• Generic namespace specification (inspired by MLton)
