+    \item Common conversion types are: gz, bz2, sha256sum, bmap\dots
+    \item This is done through a class that inherits from
+      \code{image_types}.
+    \item It has to define a function named \code{CONVERSION_CMD_<type>}.
+    \item Append it to \code{CONVERSIONTYPES}
+    \item Append valid combinations to \code{IMAGE_TYPES}
