We have this nice `runExecline` now, so we don’t need to use `runCommand` (which spawns bash) just to write a simple script.

# Takes a derivation and a list of binary names
 | 
						|
# and returns an attribute set of `name -> path`.
 | 
						|
# The list can also contain renames in the form of
 | 
						|
# `{ use, as }`, which goes `as -> usePath`.
 | 
						|
#
 | 
						|
# It is usually used to construct an attrset `bins`
 | 
						|
# containing all the binaries required in a file,
 | 
						|
# similar to a simple import system.
 | 
						|
#
 | 
						|
# Example:
 | 
						|
#
 | 
						|
#   bins = getBins pkgs.hello [ "hello" ]
 | 
						|
#       // getBins pkgs.coreutils [ "printf" "ln" "echo" ]
 | 
						|
#       // getBins pkgs.execline
 | 
						|
#            [ { use = "if"; as = "execlineIf" } ]
 | 
						|
#       // getBins pkgs.s6-portable-utils
 | 
						|
#            [ { use = "s6-test"; as = "test" }
 | 
						|
#              { use = "s6-cat"; as = "cat" }
 | 
						|
#            ];
 | 
						|
#
 |

#   provides
 |

#     bins.{hello,printf,ln,echo,execlineIf,test,cat}
