OpenVAF is an innovative Verilog-A compiler.  It translates Verilog-A
compact device models (e.g. BSIM, PSP, HICUM) into OSDI shared objects
(.osdi) that circuit simulators load at run time.  In ngspice (>= 39,
OSDI interface) a model is compiled and used like this:

    openvaf mymodel.va          # produces mymodel.osdi
    # in the ngspice .control block / netlist:
    pre_osdi mymodel.osdi

This package installs release 23.5.0, the official upstream, statically
linked x86_64 executable, as /usr/bin/openvaf.  It is a *precompiled*
binary: OpenVAF is built against LLVM 15 (the community fork
OpenVAF-Reloaded needs LLVM 18), neither of which ships with Slackware
15.0, so compiling from source is impractical here.  The binary links
LLVM statically and only needs a glibc >= 2.15 system, so it runs on
Slackware 15.0 regardless of the system LLVM version.

This release emits OSDI version 0.3, which matches the ngspice OSDI
loader.
