Thank you Stephen.
When you say 'others rely on them'..Why do they rely on them? I get
the feeling that there is some feature or property that some ppl find
important enough to use them (over the other libraries).
My first attempt at creating symbols is with DJboxsym. It was
successful but the second two bullet points at the website made for
more questions without answers that could possibly throw up roadblocks
further down the road:
1. symbols are in my "compromise' format......ummmm HOW compromised?
What is compromised?
2. No DRC support (use my sym2/csv2sym programs for that). What the
heck is DRC (not spelled out anywhere - first rule in writing a
document that I learned in grade school was ALWAYS spell out an acronym
the first time it is used), and now I need another special program that
does what??? And how does it alter the route to attaining my goal??
As an enduser, I personally don't care if it is written in perl,
python, pascal, smalltalk, lisp, algol68 or Cray Fortran. As a
developer, it may be important.
As a result, thinking that there is something 'non-native' in this
approach, I looked for others.
BTW, the link does not work - Wireshark informs me that the route is
established but does not respond..time out error.

I'd guess the majority of the community don't use it, but there are
certainly some who rely on it.

Sorry, there is no agreed 'best' way. Various members of the
community use the tools in widely varying ways. The tools are
flexible enough to work well for for applications ranging from AC
power wiring looms to ASIC layout.

I sometimes use that method, but my current work is with FPGAs and I
find the best way for making the symbols I need is DJboxsym:

This tool is very convenient for my FPGA work, but when I'm working
with BJTs, FETs, diodes and triacs I use the graphical route.
