hsenv

Creates a .hsenv/ directory that sandboxes GHC, cabal, and all packages, preventing conflicts with global or user environments as described in the basic usage.

Supports using different GHC versions than the system, including automatic downloading from remote repositories, demonstrated in the advanced usage with --ghc flag.

Allows creating multiple named environments within a single directory, enabling different configurations for the same project without recompilation, as shown with --name option.

Works with standard Haskell tools like ghc and cabal, and includes a simple Emacs mode for editor activation, integrating into existing workflows without heavy wrappers.
