Copy the files of all/specific components to install locations.

Usage: cabal v1-copy [FLAGS]
   or: cabal v1-copy COMPONENTS [FLAGS]

Components encompass executables and libraries. Does not call register, and
allows a prefix at install time. Without the --destdir flag, configure
determines location.

Flags for v1-copy:
 -h, --help                   # Show this help text
 -v[n], --verbose[=n]         # Control verbosity (n is 0--3, default
                                verbosity level is 1)
 --builddir=DIR               # The directory where Cabal puts generated build
                                files (default dist)
 --cabal-file=PATH            # use this Cabal file
 --keep-temp-files            # Keep temporary files.
 --destdir=DIR                # directory to copy files to, prepended to
                                installation directories

Examples:
  cabal v1-copy               All the components in the package
  cabal v1-copy foo           A component (i.e. lib, exe, test suite)
The v1-copy command is a part of the legacy v1 style of cabal usage.

It is a legacy feature and will be removed in a future release of
cabal-install. Please file a bug if you cannot replicate a working v1- use
case with the nix-style commands.
