Eelco Dolstra 7dfbf0eba7 * Move the substitution functions into stdenv (not merged yet).
* If the environment variable buildCommand is set, then eval that
  instead of doing the build phases.  This is used by the runCommand
  function in all-packages.nix to allow one-lines like

    foo = runCommand "foo" {} "mkdir $out; echo foo > $out/foo";

Eelco Dolstra 05c884b471 * Utility: the generic substituter. It substitutes all occurences of
`@var@' in the file `src', writing the result to $out, where `var'
  is any environment variable starting with a lowercase character.
  Example:

    genericSubstituter {
      src = ./file;
      foo = "bla";
      shell = bash + "/bin/sh";
    };

  will replace `@foo@' with `bla' and `@shell@' with
  `/nix/store/...-bash-.../bin/sh'.

Eelco Dolstra cbdd91f2a6 * Some utility functions to make performing substitutions in text
files easier.  Examples:

    substitute inputFile outputFile \
      --replace "@bindir@" "$out/bin" \
      --replace "@gcc@" "$GCC/bin/gcc"

    substitute inputFile outputFile --subst-var out

      (this is sugar for --replace "@out@" "$out")

    substituteInPlace file --replace a b

      (input and output are both `file'; the execute bit is preserved)
