/* 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" }
RCDATA NS_INFO_FileExtents { "avi|",
                             "flc\0" }
RCDATA NS_INFO_FileOpenName{ "MMOS2 video player(*.avi)|",
                             "MMOS2 Flc/Fli player(*.flc)\0" }

RCDATA NS_INFO_FileVersion       { 1,0,0,1 }
RCDATA NS_INFO_CompanyName       { "Netscape Communications\0" }
RCDATA NS_INFO_FileDescription   { "NPAVI32 Extension DLL\0"
