NAME

       pads_backannotate  - backannotates changes from a PADS engineering change order (ECO) file
       to schematic

SYNOPSIS

       pads_backannotate -h|--help

       pads_backannotate -V|--version

       pads_backannotate [options] ecofile.eco infile1.sch [infile2.sch ...]

DESCRIPTION

       The pads_backannotate program reads an engineering change order (ECO)  file  generated  by
       the  PADS  program  and  backannotates  the  requested  changes  to  a gschem schematic or
       schematics.  Refer to the PADS manual for a complete description of the ECO file format.

OPTIONS

       -h, --help
              prints help message and exits

       -n, --nocopy
              Leave the modified schematic files in  new  files  whose  names  are  generated  by
              appending  .new  to  the  original  file  names.   The  default is to overwrite the
              original.

       -v, --verbose
              operate verbosely

       -V, --version
              prints version information and exits

EXIT STATUS

       pads_backannotate will return 0 if all  files  processed  successfully,  non-zero  if  the
       command did not complete successfully.

BUGS

       Rather  than  parsing  and  processing  schematic  files  directly, this utility should be
       rewritten using the gEDA scheme API.  This would take advantage of  the  existing  parsers
       for the schematic files.

       Reference designator renaming is fully supported.  Pin and gate swapping is parsed but not
       automatically applied to the schematic database.  Instead, a report listing the manual pin
       and  gate swapping that is required.  The other features of the ECO file are not supported
       yet.
