Usage:
  features [options] <xml database> [<xml database> <xml database> ...]

Generation of C++ header file and IBY file for the given featuremanger 
database file. It also generates features DAT file for the given 
featuemanager/featureregistry database file

Options:
   -r or --hdrfile[=<destination path>] - generates only header file
   -i or --ibyfile[=<destination path>] - generates only IBY file
   -d or --datfile[=<destination path>] - generates only features.DAT file
   -c or --convert[=<destination path>] - converts feature registry database
   
   -s or --strict        - enable strict mode
   -v or --verbose       - enable verbose mode
   -h or --help          - displays this help
   
   --version             - displays the tools version

Ex: option combination \"-ri\" generates header and IBY files
   
Default destination paths:
   <header file>         - $EPOCROOT\\epoc32\\include\\
   <iby file>            - $EPOCROOT\\epoc32\\rom\\include\\
   <features.dat file>   - generates in current directory
   
Note: The conversion(--convert) of feature registry database requires the 
feature registry dtd file(featureuids.dtd) in $EPOCROOT\\epoc32\\tools\\
