Detailed Description

file extension to mimetype mapping for the GTK frontend

allows GTK frontend to map file extension to mime types using a default builtin list and /etc/mime.types file if present.

mime type and content type handling is derived from the BNF in RFC822 section 3.3, RFC2045 section 5.1 and RFC6838 section 4.2. Upshot is their charset and parsing is all a strict subset of ASCII hence not using locale dependant ctype functions for parsing.
