Eelco Dolstra 29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

A list of NTLM/NTLMv2 authenticating HTTP proxies.
Parent proxy, which requires authentication. The same as proxy on the command-line, can be used more than once to specify unlimited
number of proxies. Should one proxy fail, cntlm automatically moves on to the next one. The connect request fails only if the whole
list of proxies is scanned and (for each request) and found to be invalid. Command-line takes precedence over the configuration file.
