Let's use a simple (unflipped) fold and break out the actual core stripPrefix function from stripAnyPrefixes (I personally love point-less^H^H^H^Hfree style but if I'd be anal I'd even go further and factor away the "fn:"). Also, let's use path as a better name for "fn" (filename), because that's what it is and also cannot be confused with "fn" meaning "function". We now toString all of the prefixes, so there shouldn't be any need to implicily toString the extraSources anymore. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
To build the manual, you need Nix installed on your system (no need
for NixOS). To install Nix, follow the instructions at
https://nixos.org/nix/download.html
When you have Nix on your system, in the root directory of the project
(i.e., `nixpkgs`), run:
nix-build nixos/release.nix -A manual.x86_64-linux
When this command successfully finishes, it will tell you where the
manual got generated.
