# 0.2	09/06/99	Always include symbols from E32 and device drivers.
# 0.3	15/06/99	Added rombase flag & argument.
# 0.4	11/11/99	Remove c++filt step. Ensure symbols don't contain spaces.

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
