== 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
