+$NAME - convert a DRM1 .lit file to .epub
+
+Usage: $NAME input.lit [ output.epub ]
+
+Default output file is written to the current directory, named after the
+input filename with the .lit or .LIT extension changed to .epub, or the
+input filename with .epub appended, if there is no .lit extension.
+
+Use - for the output file, to output to stdout.
+
+Exit status is 0 on success, non-zero on failure.
+
+If you need to convert a non-DRM1 .lit file, use convertlit to downconvert
+to DRM1 first.
