+  \brief The PolyUncompressor class is a class for uncompressing
+  compressed files.
+
+  This subclass of Uncompressor contains a parameterized
+  command for doing the uncompression
+
+  It has an uncompressFile() function you call to do the
+  actual uncompression.
+ */

+/*!
+  The constructor takes the list of filename \a extensions,
+  which it passes to the base class, and the \a commandFormat,
+  which it stores locally. The \a commandFormat is a command
+  template string.
