== issues ==
the footpint SOT223 is there but the name should have been SOT-223
can't copy paste from one schematic to an other schematic
can't snap objects origin points to closed grid point to align objects
quality assurance, commit reviews for symbols and footprints
WARNING: Found a placeholder/missing component, are you missing a symbol file? [ld1117-1.sym]
^-> needed to do: cp --verbose ~/.gEDA/gschemrc ~/openarm/working/gschem/gafrc
I can deleted my schematic by doing a drccheck on it and output on the input document with no warning at all...

== todo ==
create non m4 SOT-223 footprint
create terminal block 2x1 footprint
create good 0805 footprint
