+\subsubsection{packages}
 The \t{packages} file is used to define the `system set' for this profile.
 After the above rules for inheritance and comments are applied, its lines must take one of two
 forms: a package dependency specification prefixed by \t{*} denotes that it forms part of the
 system set. A package dependency specification on its own may also appear for legacy reasons, but
 should be ignored when calculating the system set.
 
-\subsection{packages.build}
+\subsubsection{packages.build}
 The \t{packages.build} file is used by Gentoo's Catalyst tool to generate stage1 tarballs, and has
 no relevance to the operation of a package manager. It is thus outside the scope of this document,
 but is mentioned here for completeness.
 
-\subsection{package.mask}
+\note At the time of writing, Catalyst does not support \t{packages.build} as a directory.
+
+\subsubsection{package.mask}
 \t{package.mask} is used to prevent packages from being installed on a given profile. Each line
 contains one package dependency specification; anything matching this specification will not be
 installed unless unmasked by the user's configuration.

-\subsection{package.provided}
+\subsubsection{package.provided}
 \t{package.provided} is used to tell the package manager that a certain package version should be
 considered to be provided by the system regardless of whether it is actually installed. Because it
 has severe adverse effects on USE-based and slot-based dependencies, its use is strongly deprecated
 and package manager support must be regarded as purely optional.
 
-\subsection{package.use}
+\subsubsection{package.use}
 The \t{package.use} file may be used by the package manager to override the default USE flags specified
 by \t{make.defaults} on a per package basis.  The format is to have a package dependency specification,
 and then a space delimited list of USE flags to enable.  A USE flag in the form of \t{-flag} indicates
 that the package should have the USE flag disabled.  The package dependency specification is limited to
 the forms defined by the directory's EAPI.
