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 interactive 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 expansion: -// * %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. -// -// -// There are 2 possible formats for mime.types file, one entry per line (used -// for global mime.types and called Mosaic format) and "expanded" format where -// an entry takes multiple lines (used for users mime.types and called -// Netscape format). -// -// 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: -// -// b) for "expanded" format: -// type= BACKSLASH -// desc="" BACKSLASH -// exts="" -// -// (where BACKSLASH is a literal '\\' which we can't put here because cpp -// misinterprets it) -// -// 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. - -// ---------------------------------------------------------------------------- -// wxGNOME -// ---------------------------------------------------------------------------- - -// GNOME stores the info we're interested in in several locations: -// 1. xxx.keys files under /usr/share/mime-info -// 2. xxx.keys files under ~/.gnome/mime-info -// -// The format of xxx.keys file is the following: -// -// mimetype/subtype: -// field=value -// -// with blank lines separating the entries and indented lines starting with -// TABs.
