-
-  FetchCmd:
-    cabal-install stores packages in [config-dir]/packages/ by their package id.
-    This can lead to clashes if there's two identical (same name, same version)
-    packages from two servers with different functionality.
-  CleanCmd:
-    Removes all fetched packages.
-  UpdateCmd:
-    Queries all known servers for their packages and stores it in [cfg-dir]/pkg.list.
-  InstallCmd:
-    Installed packages are determined, and dependencies of the to-be-installed packages
-    are resolved and fetched.
-    The fetched tarballs are moved to a temporary directory (usually /tmp) and extracted.
-    Distribution.Simple.SetupWrapper is used to configure, build and install the
-    unpacked package. The user can
-    only pass arguments to the 'configure' phase of the installation. '--user' is used
-    by default.
-  InfoCmd:
-    To be written.
-
-  Files used by cabal-install:
-    [cfg-dir]/config        configuration file
-    [cfg-dir]/00-index.tar         list of packages available from the servers.
-    [cfg-dir]/packages/        directory containing all fetched packages.
