 To do so:
 
   - Install the dependencies (see 'Requirements' above) and build tools using

-    profile:
-
-    - autoconf
-    - automake
-    - bzip2
-    - gcc
-    - gettext

 * How It Works
 
 Guix does the high-level preparation of a /derivation/.  A derivation is
 the promise of a build; it is stored as a text file under
-=/nix/store/xxx.drv=.  The (guix derivations) module provides the
+=/gnu/store/xxx.drv=.  The (guix derivations) module provides the
 `derivation' primitive, as well as higher-level wrappers such as
 `build-expression->derivation'.
