The problem is that on John's computer, something is messed up in the latex installation so dvipdfm fails to find cmr17.tfm. One way to avoid problems like this is to include the .dvi file in the distribution. That way make doesn't ever try to rebuild it unless the user has been editing the .tex files.

It is an anti-spam measure, that usually works very well, with very few false positives, and gives a proper bounce on false positives, rather than just throwing it away. It also exposes ISP's that do not configure their mail relay correctly. Basically, what it says is that your mail relay is not what it says it is. It presents false identification. Most spam looks like this. There are 3 strategies used for spam control ... 1. Identity checking Check to see if the sender is really who he says he is. Your ISP presents false identification. Very few ISP's do this. Also, check to see if the delivery agent is authorized to deliver mail from you. Very few ISP's do this. 2. "Redlining". Check to see if the mail comes from a "bad neighborhood". Reject if it does. This is the primary defense used by AOL and similar providers. It tends to catch the same ones as identity checking, but in a more corporate friendly manner. That is, it avoids embarrasing large providers with incompetent administrators, and discriminates against small sites. Most small sites that encounter this automatically try again with laundering (pass through an agent that is friendly to them) and get though, or they just launder everything and loose tracking of their mail. 3. "Censorship" ... They look at the content and reject anything with content they don't like. This is the second defense used by many providers. It scares me more than spam. gnu.org uses another method, which is completely ineffective: Ask: "will you accept mail from me?" There are some providers that reject gnu by redlining. Gnu, in retaliation, rejects mail from them. It is annoying, and accomplishes nothing in reducing spam. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

That's the reason I wrote this new feature. People like you are the ones
who may use this kind of tool.
If you look for "default-position-of-text-attributes" in your
system-gschemrc file, you will find the default position definition of
pin and component attributes.
I think you can adapt it to your norms and let gschem to do the hard
work for you.
Let me explain:
For component attributes, there are 4 sections:
- one direction: components having pins in only one side. '<' means the
symbol have pins on the right side.
- two directions: components having pins in two sides. "<>" means the
symbol have pins on left and right side.
- 3 directions, and
- 4 directions are similar
These sections are there for different component angles. A vertical
resistor will have pins on the top and on the bottom ("^v") while an
horizontal resistor will have them on the right and on the left ("<>").
So if we analyze what a configuration line means, for example:
; Two directions
; Name Direct. X_offset Y_offset Reference Alignment Angle
("refdes" "<>"-50 50 "Upper Middle" "Lower Right"0)
This line is defining the default place for those "refdes" attributes
for components having pins on the left and on the right ("<>", second
entry).
The default place is the "Upper Middle" (reference) of the symbol (i.e.:
at the top (Y axis), in the middle (X axis)), with a x offset of 50 mils
to the left, and an y offset of 50 mils to the top.
The text alignment is "Lower right" and the text angle is 0.
Using this feature, you can define the places where you want the
attributes, and let gschem to place them for you, even when rotating or
mirroring the component.
You don't have to wonder if the symbol has the attributes placed where
you want them.
>From your comment, I guess the refdes attribute position depends on the
type of the symbol: if it's a resistor or a capacitor then you want it
at one place, but if it's an IC, then you put it at another place. Am I
right?. This is not currently possible, but I think it could be done.
I'd really appreciate if you could give this new feature a try and let
me know what points can be improved.
Thanks,
Carlos
