**** Fix test warnings on 32-bit Perls.
**** Fix missing uint32_t definition on Fedora, bug100. [Lane Brooks]
**** Work around compiler warning when using flex 2.5.35. [Jonathan Kimmitt]
**** SP_COVERGROUP timing windows can now have options/illegal/ignore/limit
like other coverpoints.
**** Fix test failure on 32-bit systems. [Brennan Ashton]
** This package is now licensed under LGPL v3 and/or Artistic v2.0.
** Verilog-Perl 3.200 or newer is required to run this version.
*** Add signal and direction regexp to AUTOINOUT_MODULE. [Brian Cassell]
*** Include list of "use"d files in .sp_tree report.
*** Fix tracing Verilog escaped identifiers with dots getting mis-scoped.
**** Respect #sp ifdef's in coverage groups.
**** Fix warning about README on git installs. [Brian Small]
** Created SYSTEMPERL_INCLUDE which if set allows relocating the
src directory.
*** The systemc-mode.el provided now just calls c++-mode. This solves
many Emacs 22 incompatibilities, and does enough for now.
**** The README was converted into pod format to create SystemC::Manual.
**** Added SpCoverage::write data can now be filtered by a string.
**** Fix compile error with Bison 2.4.1. [Chitlesh Goorah]
** Further refinements of coverage. [by Robert Woods-Corwin]
** SP_COVER_INSERT now only accepts char* keys and values.
This prevents GCC 4.2.1 from running out of memory.

**** SpCoverage dumps are now written in the faster binary format.
**** Fix parsing comments at end of "#sp ifelse" lines. [Brian Cassell]
**** Fix parsing sp_ui as basic type. [Prabhat Gupta]
** Many improvements to coverage, including coverage groups and automatic
binning - see the documentation for details. [by Robert Woods-Corwin]
** The SP_COVERAGE define must now be set when doing coverage.
This accelerates compilation and run-time when not using coverage.
** Coverage across multiple hierarchies is now compressed together,
as per the SystemVerilog standard. Use SP_COVER_INSERT(...,
per_instance,1) to override this behavior.
*** Added "#sp slow" directive for splitting up large files into
portions that can be compiled with less aggressive optimization.
**** Support more arguments to SP_COVER_INSERT. [by Robert Woods-Corwin]
**** Fix string.h compile error. [Rodney Sinclair]

**** Fix whitespace in sp preprocessor directives, "# sp use ...".
**** Fix some RedHat 9.0 warnings
*** Allow "sp use DEFINE" where DEFINE is a symbol like ALIAS_CELL

**** Report warning if SP_TRACED variables aren't traced. [Greg Waters]
**** Allow enum values to initialize to symbolic constants. [Greg Waters]
**** Use low level I/O routines to improve tracing by 30%.
**** Have AUTOTRACE use values from the module that generates the signal
rather than the top level. With Verilator, tracing is 10% faster.
**** Support bison 1.75
** Support SystemPerl version 2.0.1. A patch is required for tracing
input signals and sc_bv types, see the the README file.
*** Add example of SP_COVER statement.
*** Put AUTOINOUT signals under that label, so they can be public
while AUTOSIGNALs can be private. [Greg Waters]
*** Support signals in inherited sc_modules. [Navit Fedida]
*** Support modules declared as inherited from sc_module. [Navit Fedida]
**** Allow traced modules to determine if they might have any activity.
Used for Verilator3 to improve trace speed by about 60%.
** Added Emacs mode in systemc-mode.el
** Added #sp use "filename", for determining link objects automatically.
*** Allow modules not specified on the command line to be found
automatically by using the search path (ala Verilog.)
**** SystemC::Parser now emits a separate text() callback for the text
of a AUTO. This allows programs to more easily replace the text inline.
**** Improve tracing to allow smaller files, rollover, inlining child traces.
** Moved Netlist guts into Verilog package,
made SystemPerl a derived class. This allows mixed-mode netlists.
** $SYSTEMPERL should now point to the root of this package,
not the root/src directory.
*** Include header guards in .cpp file so that multiple CONCAT
inclusions with sp_includer work OK.
*** Allow tracing of sc_bv<>'s
**** Addition of experimental sclite library
for testing package without SystemPerl installed.
** Added #sp include directive. [Experimental, some crashes]
** AUTOMETHODS is the new name for AUTODECLS
AUTOMETHODS will create a SC_CTOR(__MODULE__); if there is not
already one in the class interface.
** AUTOTRACE uses a internal library to trace ports.
AUTOTRACE should work on all clocks, ports, arrays, etc, and
any simple types marked with SP_TRACED.
AUTOTRACE requires AUTOMETHODS to be used in the class interface.
** The #include systemperl.h at the top of all .h files has been removed.
It must be included manually. This allows systemperl to be used in
non-systemc applications.
*** AUTOENUM ascii() method implementations are now put in the .cpp
rather than the .h file. This is indicated by a AUTOIMPLEMENTATION
section, which is inserted automatically at the bottom of the .cpp
file if not elsewhere in the file.
*** Detect and report unterminated strings, automodes, comment blocks.
*** Handle character constants ('a', '\0'). Handle octal and hex
escape sequences in strings and char-constants.
*** Handle nested typenames (e.g. sc_out<ClassFoo::EnumBar>).
** Added AUTOSUBCELL_INCLUDE and AUTOSUBCELL_CLASS
** Extracted SystemC::Template for other programs needing #line'd files.
** Comments are now properly extracted for signals & ports.
Note such comments must begin on the same line as the declaration.
*** Fixed extra #line statements in output files.
*** Added directional comment to /AUTOINST/ created pins.
*** Fixed bug with recognizing sc_inouts. [Amir Sahar]
** Added AUTOTRACE for creating trace statements for all signals.
** Added sp_includer and sp_makecheck for faster SystemPerl compiles.
*** Added sp_preproc --libcell for cells that are not to be expanded.
This is useful for hierarchical sp_preproc'essing.
** Added AUTOENUM_* for ascii displays of enum values.
** Added SP_CTOR_IMP for constructors outside of the class decl.
** Added SP_CELL_DECL, and allowed arrayed cell declarations.
** Added SP_CELL_FORM for printf formatting of cell name.
** Fixed class x {enum y}, class z {enum y} problem.
*** Fixed test on Solaris Linux.
**** The debugging dump methods are now ->dump, not ->print.
** sc_clocks are now recognized as signal declarations.
** sc_main is considered similar to a SC_MODULE(sc_main)
**** Support Perl 5.005_003 and non-GCC
**** Many, Many bug fixes.
