/* The OS/2 version of Netscape uses RC_DATA to define the
   mime types, file extensions, etc that are required.
   Use a vertical bar to separate types, end types with \0.
   FileVersion and ProductVersion are 32bit ints, all other
   entries are strings the MUST be terminated wwith a \0.

AN EXAMPLE:

RCDATA NS_INFO_ProductVersion { 1,0,0,1,}

RCDATA NS_INFO_MIMEType    { "video/x-video|",
                             "video/x-flick\0" }
