* src/spicelib/parser/inpptree-parser.y ,
* src/spicelib/parser/inpptree.c :
bug fix, allow special nodenames "/Node" and "Node-4" in `B' expressions
related to
http://sourceforge.net/tracker/?func=detail&aid=3421234&group_id=38962&atid=423915
the lexer will now identify special function applications
v(node) v(node,node) and i(instance)
2011-10-02 Holger Vogt
* device.c updates to altermod command, allow reading from file with
multiple .model sections
2011-09-18 Holger Vogt
* com_fft.c: fft now uses faster Green's method (may be deselected by unsetting
#define GREEN swirch
* spiceif.c: code beutify for better readability
* device.c updates to altermod command, allow reading from file
* device.c updates to altermod command, allow reading from file
* com_measure2.c: warning real ac removed
2011-09-11 Holger Vogt
* frontend/plotting/grid.c: Error message, if requested resolution
cannot be handled.

* /admst/ngspice.xml, ngspiceVersion.xml, psp102.va: psp102 module name change
* /admst/ngspice.xml, ngspiceVersion.xml, psp102.va: psp102 module name change
according to model developer used naming convention (psp102 is now PSP102VA)
2011-08-24 Dietmar Warning
* configure.ac, inp2q.c, inpdomod.c, dev.c, ngspice.xml, bjt504t.va:
change the name of the mextram verilog module according to model developer
change the name of the mextram verilog module according to model developer
used naming convention (mextram.va is substituted by bjt504t.va), means
including parasitic substrate transistor and selfheating is enabled
