 215 // this class uses both mailcap and mime.types to gather information about file
 216 // types.
 217 //
 218 // The information about mailcap file was extracted from metamail(1) sources and
 219 // documentation.
 220 //
 221 // Format of mailcap file: spaces are ignored, each line is either a comment
 222 // (starts with '#') or a line of the form <field1>;<field2>;...;<fieldN>.
 223 // A backslash can be used to quote semicolons and newlines (and, in fact,
 224 // anything else including itself).
 225 //
 226 // The first field is always the MIME type in the form of type/subtype (see RFC
 227 // 822) where subtype may be '*' meaning "any". Following metamail, we accept
 228 // "type" which means the same as "type/*", although I'm not sure whether this
 229 // is standard.
 230 //
 231 // The second field is always the command to run. It is subject to
 232 // parameter/filename expansion described below.
 233 //
 234 // All the following fields are optional and may not be present at all. If
 235 // they're present they may appear in any order, although each of them should
 236 // appear only once. The optional fields are the following:
 237 //  * notes=xxx is an uninterpreted string which is silently ignored
 238 //  * test=xxx is the command to be used to determine whether this mailcap line
 239 //    applies to our data or not. The RHS of this field goes through the
 240 //    parameter/filename expansion (as the 2nd field) and the resulting string
 241 //    is executed. The line applies only if the command succeeds, i.e. returns 0
 242 //    exit code.
 243 //  * print=xxx is the command to be used to print (and not view) the data of
 244 //    this type (parameter/filename expansion is done here too)
 245 //  * edit=xxx is the command to open/edit the data of this type
 246 //  * needsterminal means that a new console must be created for the viewer
 247 //  * copiousoutput means that the viewer doesn't interact with the user but
 248 //    produces (possibly) a lof of lines of output on stdout (i.e. "cat" is a
 249 //    good example), thus it might be a good idea to use some kind of paging
 250 //    mechanism.
 251 //  * textualnewlines means not to perform CR/LF translation (not honored)
 252 //  * compose and composetyped fields are used to determine the program to be
 253 //    called to create a new message pert in the specified format (unused).
 254 //
 255 // Parameter/filename xpansion:
 256 //  * %s is replaced with the (full) file name
 257 //  * %t is replaced with MIME type/subtype of the entry
 258 //  * for multipart type only %n is replaced with the nnumber of parts and %F is
 259 //    replaced by an array of (content-type, temporary file name) pairs for all
 260 //    message parts (TODO)
 261 //  * %{parameter} is replaced with the value of parameter taken from
 262 //    Content-type header line of the message.
 263 //
 264 // FIXME any docs with real descriptions of these files??
 265 //
 266 // There are 2 possible formats for mime.types file, one entry per line (used
 267 // for global mime.types) and "expanded" format where an entry takes multiple
 268 // lines (used for users mime.types).
 269 //
 270 // For both formats spaces are ignored and lines starting with a '#' are
 271 // comments. Each record has one of two following forms:
 272 //  a) for "brief" format:
 273 //      <mime type>  <space separated list of extensions>
 274 //  b) for "expanded" format:
 275 //      type=<mime type> \ desc="<description>" \ exts="ext"
 276 //
 277 // We try to autodetect the format of mime.types: if a non-comment line starts
 278 // with "type=" we assume the second format, otherwise the first one.
 279
 280 // there may be more than one entry for one and the same mime type, to
 281 // choose the right one we have to run the command specified in the test
 282 // field on our data.
