# Tries to fix eagle schematic to board discrepancy if some one ascendantly changes values in schematic while
# the board file was not connected

# To avoid gotchas copy the board file into t.brd, it will be edited in place.
# Once you happy with fixes overwrite the original eagle board file with t.brd

# Look thought the diff and file list of parts with updated values
git diff | grep '+<part name="' |sed s/'+<part name="\([^"]*\)".*value="\([^"]*\).*'/'\1 \2'/ >part.list

# Now update components values in the board file.
# Assumes that board file is copied into t.brd file
cat part.list | \
