Usage:
  hpsym [-r <rombase>] <logfile> [<outfile> [<executables>]]

Where:
  <rombase>     Offset in hex of logical address from physical address of ROM.
                Defaults to 50000000. Use 0 for single-process builds.
  <logfile>     Log from maksym tool.
  <outfile>     Output filename. Default is 'symbols.gpa'. Use - for stdout.
  <executables> Names of additional executables to list the symbols of.
                ASSP-specific executables and EUSER are always included.

Example:
  hpsym maksym.log symbols.gpa efile efsrv .fsy

EOF
