+or files and write output to temporary files. Similarity to mailcap
+is config file. You can assign various file externsions with DGI, and
+run to get output.
+
+See Arachne documentation for details of configuration file mime.cfg.
+
+Note, that not all options were implemented in ELinks, and not all were tested.
