	A more lightweight alternative is to use <code>nix-shell</code> in the shebang line as described in this [http://iam.travishartwell.net/2015/06/17/nix-shell-shebang/ blog post]. This causes the expression to be evaluated and built every time the script is run; this means that the dependencies will always be kept up to date, but since nix-shell only creates a temporary GC root the dependencies may be removed by a garbage collection, so this approach is not advisable for users who don't have an internet connection available all the time.

	For scripts like a single Python file, it is not necessary to specify <code>src</code> in <code>mkDerivation</code>. When you want to use <code>buildPythonPackage</code> the sources need to provide a <code>setup.py</code> file which also is overkill for a lot of projects. The default <code>mkDerivation</code> will attempt to unpack your source code. This can be prevented ~~that~~ by applying <code>unpackPhase = ":";</code> (<code>:</code> is a no-op in shell scripts).
