# pcb\_backannotate(1)

backannotates changes from a PCB annotation file to schematic

## NAME

**pcb\_backannotate** - backannotates changes from a PCB annotation file to schematic

## SYNOPSIS

**pcb\_backannotate -h\|--help**

**pcb\_backannotate -V\|--version**

**pcb\_backannotate** \[options\] *ecofile.eco infile1.sch \[infile2.sch ...\]*

## DESCRIPTION

The *pcb\_backannotate* program reads an engineering change order (ECO) file generated by the PCB program and backannotates the requested changes to a gschem schematic or schematics. Refer to the PCB 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

*pcb\_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.
