+<body>
+
+<p>
+The <c>use.mask</c> file can be used to mark <c>USE</c> flags as unavailable on a
+particular profile. This can be useful for various reasons:
+</p>
+
+<ul>
+  <li>
+    Masking hardware-specific feature flags. For example, <c>mmx</c> and <c>sse</c> are
+    only available on x86, <c>altivec</c> is only available on <c>ppc</c> and <c>vis</c> is
+    only available on sparc v9.
+  </li>
+  <li>
+    Disabling unavailable soft dependencies. A simple hypothetical example <d /> say
+    <c>fooapp</c> works on <c>mips</c>, but has an optional dependency (controlled by
+    the <c>bar</c> flag) upon <c>libbar</c>, which doesn't work on <c>mips</c>. Then by
+    adding the <c>bar</c> flag to <c>profiles/default-linux/mips/use.mask</c>,
+    <c>fooapp</c> could be made available to <c>mips</c> users with the unresolvable
+    dependency forcibly disabled.
+  </li>
+</ul>
+
+<p>
+Note that <c>use.mask</c> is a per-flag thing, not per package's use of a given
+flag. This is one of the reasons that USE flags must have a specific well
+defined purpose.
+</p>
+
+<p>
+Updates to <c>use.mask</c> should be handled via the relevant arch team.
+</p>
+
+<p>
+See `noblah USE Flags`_ for more discussion.
