Rather than having a component class, explicitly subclassed in the
database to contain resistor specific attributes, I would do it similar
to the following:
1 component class / table, one size fits all. Each has a component ID.
The Component ID is what I list on BOM.
1 attribute type class

Hi,
Recently, I talked with some people about EDA tools and they main arguments
against gEDA were:
1) no MS-windows support
2) missing components
It's very nice to see that this two topics are heavily discussed here.
