@Stefan Schippers: A small issue with xschem that I found: If I have start xschem with

--tcl 'append XSCHEM_LIBRARY_PATH :.'

it does not do the same thing as if I expand the current working directory path and add that to

XSCHEM_LIBRARY_PATH

. This came up because I was working with schematics in two different directories (both subdirectories of the same parent directory). In one of them, I had an

xschemrc

file that added

..

to the library path and was including one symbol by reference to the other (sibling) directory. That worked fine when I was running xschem in that directory. But if I ran xschem from the parent of both directories and tried to add

.

to the library path through the command line, it failed to find the symbol, unless I expanded that to the full absolute path.
