// this class uses both mailcap and mime.types to gather information about file
// types.
//
// The information about mailcap file was extracted from metamail(1) sources and
// documentation.
//
// Format of mailcap file: spaces are ignored, each line is either a comment
// (starts with '#') or a line of the form <field1>;<field2>;...;<fieldN>.
// A backslash can be used to quote semicolons and newlines (and, in fact,
// anything else including itself).
//
// The first field is always the MIME type in the form of type/subtype (see RFC
// 822) where subtype may be '*' meaning "any". Following metamail, we accept
// "type" which means the same as "type/*", although I'm not sure whether this
// is standard.
//
// The second field is always the command to run. It is subject to
// parameter/filename expansion described below.
//
// All the following fields are optional and may not be present at all. If
// they're present they may appear in any order, although each of them should
// appear only once. The optional fields are the following:
//  * notes=xxx is an uninterpreted string which is silently ignored
//  * test=xxx is the command to be used to determine whether this mailcap line
//    applies to our data or not. The RHS of this field goes through the
//    parameter/filename expansion (as the 2nd field) and the resulting string
//    is executed. The line applies only if the command succeeds, i.e. returns 0
//    exit code.
//  * print=xxx is the command to be used to print (and not view) the data of
//    this type (parameter/filename expansion is done here too)
//  * edit=xxx is the command to open/edit the data of this type
//  * needsterminal means that a new console must be created for the viewer
//  * copiousoutput means that the viewer doesn't interact with the user but
//    produces (possibly) a lof of lines of output on stdout (i.e. "cat" is a
//    good example), thus it might be a good idea to use some kind of paging
//    mechanism.
//  * textualnewlines means not to perform CR/LF translation (not honored)
//  * compose and composetyped fields are used to determine the program to be
//    called to create a new message pert in the specified format (unused).
//
// Parameter/filename xpansion:
//  * %s is replaced with the (full) file name
//  * %t is replaced with MIME type/subtype of the entry
//  * for multipart type only %n is replaced with the nnumber of parts and %F is
//    replaced by an array of (content-type, temporary file name) pairs for all
//    message parts (TODO)
//  * %{parameter} is replaced with the value of parameter taken from
//    Content-type header line of the message.
//
// FIXME any docs with real descriptions of these files??
//
// There are 2 possible formats for mime.types file, one entry per line (used
// for global mime.types) and "expanded" format where an entry takes multiple
// lines (used for users mime.types).
//
// For both formats spaces are ignored and lines starting with a '#' are
// comments. Each record has one of two following forms:
//  a) for "brief" format:
//      <mime type>  <space separated list of extensions>
//  b) for "expanded" format:
//      type=<mime type> \ desc="<description>" \ exts="ext"
//
// We try to autodetect the format of mime.types: if a non-comment line starts
// with "type=" we assume the second format, otherwise the first one.

// there may be more than one entry for one and the same mime type, to
// choose the right one we have to run the command specified in the test
// field on our data.
