This is used to generate ppd files for cups:
$ cups-genppd.5.2 -M | grep p50
canon-cp500
escp2-p50
$ cups-genppd.5.2 -p . escp2-p50
This will create the relevant ppd file in the current directory. This
can then be used by cups after setting services.drivers.drivers =
[pkgs.gutenprint]; and configuring the printer to use this ppd e.g.
via the web interface on http://localhost:631

I don't understand the reason for the original 700 permission bits.
Apparently read-access is needed and Ubuntu also use 755 perms.
Use "chmod" instead of "mkdir -m" to set permissions because mkdir doesn't
modify permissions on existing directories.
(systemd service descriptions that is, not service descriptions in "man
configuration.nix".)
Capitalizing each word in the description seems to be the accepted
standard.
Also shorten these descriptions:
* "Munin node, the agent process" => "Munin Node"
* "Planet Venus, an awesome ‘river of news’ feed reader" => "Planet Venus Feed Reader"
1) The wrapper erroneously used the ghc-pkg flag "--package-db" instead of
"--global-package-db". The result was that packages installed locally in
~/.ghc and ~/.cabal were invisible to GHC. This has been fixed.
2) The wrapper now deals gracefully with an empty package set: if no package
is requested to be included in the wrapped environment, the wrapper just
installs a pristine GHC.
3) Correctly configure the "docdir" path returned by ghc-paths.
4) Added some comments that describe the idea behind our ghc-paths patches and
gives users same sample shell code that can be used to import our special
environment variables into the currently running shell, so that programs
outside of the wrapped environment can use them, too.
- It now uses JavaScript for configuration (only),
so I had to "convert" config for NetworkManager.
- I tested suspend/restart/(un)mount on KDE/Xfce,
Phreedom tested NetworkManager config conversion.
The firmware file needs to be downloaded or extracted from the windows
driver file and configured in nixpkgs.config e.g.:
sane.snapscanFirmware = /firmware/esfw41.bin;
