not complete, e.g.
      DERIV is missing).

Linear) functionality
      for B (arbitrary generator) sources.

Reveals an important work in compile scripts, many bug fixes in memory \ 
management, interface, and
work in device models.

    * Compile scripts: tclspice and ADMS compiling fixes. Architecture compiling \ 
fixes for SunOS,
      MS Visual Studio, MINGW, Cygwin.
    * Memory management: fixed memory leaks, modifies memory management for MS \ 
Windos, integration of
      espice bugfixes and enhancements, bug fixes in plots and cli interface.
    * Rework of BSim models, integration of EPFL-EKV model V2.63, ADMS models \ 
mextram, hicum0, hicum2.

----------------
Release 18
----------------
Rework-18 is introduces several new features into ngspice. This is a major
release that comes after more than three years. During the silent years
ngspice developers worked in CVS to stabilize and introduce new features
into the simulator.

- Tclspice simulator library has been merged with ngspice. Now you can
  compile ngapice or tclspice by asserting a configure switch. See README.tcl
- New options have been introduced: brief, listing, autostop and scale
- Support for .lib file has been introduced. This allows the use of
  third party model libraries in ngspice.
- .measure statements: avg, integ, rms, max, min, delay, param
- .global statements t support for global nodes whose name is not expanded
  when flattening the netlist.
- .func macros for inlining functions into netlists.
- Improved the numparam library to support fully parametrized netlists.
- BSIM model binning.
- new multi-input gate VCVS using XSPICE extensions.

Remove @dirrm entries from PLISTs

Log message:
Recursive ABI depends update and PKGREVISION bump for readline-6.0 shlib
major change.

Reported by Robert Elz in PR 41345.

Log message:
Bump PKGREVISION for libXaw API depends bump due to libXaw8 removal.

Log message:
Add DESTDIR support.

Log message:
Modular Xorg support.

Log message:
Fix compilation on solaris and probably other systems with a posix
wait().  Patch (or equivalent) will be applied upstream.

Log message:
* Honor PKGINFODIR.
* List the info files directly in the PLIST.

Log message:
* Teach the tools framework how to supply the pkgsrc version of
  makeinfo if no native makeinfo executable exists.  Honor TEXINFO_REQD
  when determining whether the native makeinfo can be used.

* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.

* Get rid of all the "split" argument deduction for makeinfo since
  the PLIST module already handles varying numbers of split info files
  correctly.

NOTE: Platforms that have "makeinfo" in the base system should check
      that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
      correct.
