+* changes from libg++-1.36.3 to libg++-1.37.0
+
+ * Most utility classes and functions are now in stand-alone .cc and/or .h
+ files. This should generate smaller exectuables, and, sometimes
+ faster compilation. In particular, istream.h, and ostream.h are
+ now separately includable. If you only need one, you don't have
+ to get the other.
+
+ * The Plex classes now understand `const'. The `changes' and `changed'
+ member functions were removed, since it is now possible to
+ avoid changes in Plex structures by using const versions.
+
+ * class RandomInteger is available, courtesy of John Reidl.
+
+ * PlotFile3D, a 3D plot class is in libg++/etc. It will be
+ incorporated into libg++ proper for the next release, perhaps
+ with a few changes. Thanks to Tom Ngo.
+
+ * various and sundry bug fixes, minor enhancements, and/or portability
+ improvements as described in the ChangeLog.
+
+ * The file etc/HINTS is an emacs RMAIL file that contains recent
+ bug-lib-g++ list mail and related messages that may be useful.
+
+
+* changes from libg++-1.36.1 to libg++-1.36.3
+
+ * `Tmp' classes have been eliminated from Strings, Integers, etc.
+ (Via some retuning of the main classes, Tmp classes were found
+ to not significantly impact performance one way or the other,
+ so they were removed.)
+
+ * There is now a version of malloc, directly supporting operator
+ new, etc. It may be faster and better suited to C++ applications
+ than your libc malloc. You should be able to use it unless you need
+ a special malloc for a distributed shared memory environment or
+ the like. If you can't use it, edit the appropriate flag in
+ the top-level Makefile. I would very much appreciate feedback
+ about whether this malloc makes any difference in time or space
+ efficiency than whatever you are now using.
+
+ * By default, output is now line-buffered. Use the
+ NO_LINE_BUFFER_STREAMBUF define in the Makefile to override
+
+ * Otherwise, the stream classes remain C++-1.2 compatible.
+ C++-2.0-compatible versions are still in the works.
+
+ * various and sundry bug fixes, minor enhancements, and/or portability
+ improvements as described in the ChangeLog.
+
+* changes from libg++-1.35.0 & 1.35.1 to 1.36.1
+
+ * various and sundry bug fixes, minor enhancements, and/or portability
+ improvements as described in the ChangeLog.
+
+ * Most everything should now work on most SystemV machines. Let me
+ know if they don't.
+
+ * genclass now allows an optional prefix to be used instead of type
+ name concatenation in order to help minimize filename
+ lengths for SYSV users. This is not a great solution, but
+ is A solution to filename length problems for SYSV users.
+
+ * Some, but not all classes now behave well with respect to
+ the new 2.0 const specifications. Some uncertainties about
+ how g++ will interpret gcc-based const function qualifiers
+ (to indicate lack of side effects) versus C++-2.0 const member
+ functions has held up the conversion of some classes to use
+ const in either or both of these ways.
+
+ * A version of etags suitable for use with c++ is in etc/
+ (courtesy of J. Clark)
+
+ * `graph', a unix graph(1) work-alike is in libg++/etc, courtesy
+ of Rich Murphey.
+
+ * RAVLMap (Ranked AVLs) prototypes.
+
+ * The GetOpt class & support has been moved from etc/ into libg++.a
+
+ * Streams have been redone to be nearly 100% AT&T 1.2 compatible.
+ One minor possible incompatibility exists (ostream<< char)
+ that can be eliminated via #define NO_OUTPUT_CHAR at the
+ top of stream.h. This is probably necessary in order to
+ compile et++. See libg++.texinfo for more details.
+
+ The new stream implementation is not particulary pretty.
+ Its main virtue is that it avoids some of the worst things
+ about both AT&T streams and old libg++ streams. A much
+ superior AT&T 2.0-iostream superset is in the works
+ for future release.
+
+* changes from libg++-1.25.0 to libg++-1.32.0
+
+ * Nearly all data and methods previously declared as `private'
+ are now declared as `protected' to make subclassing from
+ library classes easier.
+
+ * Most classes now contain a method `OK()' that checks to
+ make sure that an objects internal data is in a valid state.
+ See the documentation for further details
+
+ * Mosts tests in ./tests now contain various kinds of assert
+ statements. If tests execute without assertion failures,
+ and without any other errors that cause aborted execution,
+ you may consider them successful. The test files now include
+ nearly all of my internal tests, which in turn have been
+ made more extensive.
+
+ * Plex classes are available.
+ A bit of propaganda about these:
+ Plexes are very attractive replacements for arrays
+ in many contexts. Try them!
+
+ * `shrink' and `contains' have been added to Obstack
+
+ * Files and streams have not yet been revamped (a complete
+ reworking awaits the AT&T 2.0 stream specification), but
+ have been adjusted to provide slightly faster IO in some
+ cases, and now support the use of a user-supplied string
+ to read or write from instead of an actual IO source.
+
+ * Rationals are now normalized when input via `>>'.
+
+ * atoI is fixed.
+
+ * variable-length representations in String, Integer, etc., are
+ now completely different. See the documentation for details.
+
+ * New String functions:
+ * readline -- read in a line from an istream as a String
+ * prepend -- prepend stuff to a String
+ * through -- make a SubString from beginning to match point
+ * from -- make a SubString from match point to end
+ * s[i] -- now returns the char by reference
+
+ * BitVec's are no longer supported, since their capabilities
+ are now incorporated in the revised BitString class.
+
+ * stdarg.h and regex.h are revised to support the Sun4
+
+ * Several interesting and/or useful examples of libg++
+ class use are in ./etc, mainly courtesy of Doug Schmidt.
+
+ * .cc file names are now all less than 15 characters. Some
+ .h file names are longer, but this should not present
+ problems on SYSV systems.
+
+ * pseudo-generic `proto' classes have been thoroughly revised:
+ * The prototype file names now end in `P', not `.proto'
+ and are in the g++-include directory
+ * A single, simple-to-use collection traversal mechanism
+ via pseudo-indices (`Pix') is used instead of particular
+ traversal friend classes.
+ * `Bag' prototypes are included
+ * Base classes are now supplied, so that all implementations
+ of Sets, Bags, are derived, allowing programmers to
+ mix and match implementations.
+ * They are now simpler to create: all comparison operators
+ and the like are now defined as macros in a `defs' file
+ which uses some reasonable defaults.
+ * The `Dictionary' versions of Set prototypes are not now
+ supported. Revised versions of such classes are forthcoming.
+ * Class prototypes previously labelled as `Assoc' are now
+ called `Maps', with slightly different capabilities.
+
+ * Splay tree prototypes are available.
+ A bit more propaganda: Consider using Splay tree
+ based containers (Set, Bag, Map, PQ). They are often
+ the most efficient structures when performing mixtures
+ of operations (adds, deletes, searches...)
+
+ * Fixed precision reals are available, courtesy of Kurt Baudendistel
+
+ * An ordered hash Set prototype (VOHSet) is available,
+ courtesy of Doug Schmidt.
+
+ * MLCG now allows access and modifications to the seeds.
+
+ * The Normal random generator is fixed.
+
+ * SampleStatistic now allows any prob value for confidence
+ intervals.
+
+ * some simple timer routines are in builtin.cc, courtesy of Doug Schmidt
+
+ * While the Vec class prototypes are still available, they are
+ currently undergoing revision in order to correspond to
+ the forthcoming Matrix package (which should be available
+ in the next libg++ release).
+
+ * A C++ version of GPERF, a perfect hash function generator
+ program is also available in ./etc, courtesy of Doug Schmidt.
+
+
+* changes from libg++-1.22.2 to libg++-1.25.0
+
+ * All reported errors from the previous release are fixed, and many
+ suggested modifications have been performed. Thanks to all who
+ have sent bug reports and comments, including those with mail
+ addresses that I have not been able to reply to. (My mail connections
+ are sometimes more than a little fragile. If you send me mail and
+ I have not replied within a few days, you may want to try again. Sorry.)
+
+ * A serious problem in the use of Obstacks by conversion functions
+ has been repaired.
+
+ * A bug in maintaining reference counts on `find' and related operations
+ in List prototype classes has been fixed.
+
+ * Strings now support self case manipulation in addition to the
+ functional versions.
+
+ * Some new functions have been added to builtin.[h.cc]. All are now
+ documented in libg++.texinfo
+
+ * Overload declarations are now performed in std.h and math.h,
+ rather than builtin.h, to eliminate some include file ordering
+ problems.
+
+ * Random, RNG, and SampleStatistic classes are available,
+ thanks to Dirk Grunwald.
+
+ * A BitVec class is available.
+
+ * The are many new generic container class prototype files. These
+ support container classes based on elementary data structures
+ (and a couple of non-elementary ones). Please read the documentation.
+
+ * Class prototype OSet has been modified and renamed OLSet.
+
+ * The genclass utility has been modified
+
+* changes from libg++-1.22.1 to 1.22.2
+
+ * Tests files are now in a separate directory.
+
+ * Several minor errors (Complex unary -, several BitString functions)
+ have been repaired.
+
+ * pow(0,0) returns 1 for all versions of pow.
+
+ * An experimental generic class prototyping feature is provided,
+ including prototypes for lisp-style lists and ordered list-based sets.
+
+ * several include files with the same names as those in AT&T CC
+ are provided. These simply #include other files. OOPS should now
+ compile using only g++-include files. See, however, the note
+ about struct exception in file math.h
+
+ * Some rearrangement of files containing char* conversion has been
+ done to eliminate linking of unnecessary classes.
+
+ * The inline-only-when-optimizing feature is still not supported.
+
+* New Random number generator classes are not yet available. Stubs for
+ these files are in this directory. They should be available for next
+ release.
+
+* changes from libg++-1.21.1 to 1.22.0
+
+ * All documentation is in a stand-alone texinfo file, libg++.texinfo,
+ and is on its way to becoming a decent piece of documentation.
+
+ * All reported errors from the previous release are fixed, and many
+ suggested modifications have been performed. Thanks to all who
+ have sent bug reports and comments, including those with mail
+ addresses that I have not been able to reply to. (My mail connections
+ are sometimes more than a little fragile. If you send me mail and
+ I have not replied within a few days, you may want to try again. Sorry.)
+
+ * New Complex, BitSet, and BitString classes are available. You will
+ be performing a valuable service if you try these out and report
+ back any bugs/comments/suggestions about these or any other classes.
+
+ * File `values.h' has been added. This contains various system
+ constants like the number of bits per long, etc. It contains
+ much of the same information as sun <values.h>, although a
+ few names and things differ slightly.
+
+ * Files `builtin.h', `builtin.cc', and `convert.cc' have been added.
+ `builtin' contains common inline and non-inline functions on
+ builtin types (like `abs'). `convert' contains code for performing
+ IO and char* conversions, mainly via Obstacks. Most of these
+ functions are not new -- they have been collected from other .h
+ and .cc files.
+
+ * Files `std.h' and `math.h' now declare all libc.a C functions
+ in a way that allows any of them to be overloaded in C++.
+
+ * Strings and Integers now perform expansion via realloc() --
+ see libconfig.h about whether you should #define SHOULD_FREE_TO_REALLOC.
+
+ * `eatwhite' is supported for istreams.
+
+ * File::getline(String, ...) and get(String) have been removed in order to
+ maintain greater independence of different classes.
+
+ * Strings now provide substring matching via new versions of
+ `contains' and `matches', `common_prefix' and `common_suffix'.
+ Also, there is more support for case operations via `fcompare', etc.
+ The versions of `decompose' that do not deal with Regexes have
+ been deleted since they provide little functionality over other
+ operations. Also, a few special case functions dealing with char*'s
+ have been deleted since the required constructors are necessary
+ anyway. Several other corrections have been made in String.cc,
+ including the elimination of a few aliasing problems.
+
+ * The implementations of Integers and Rationals are now both much
+ more efficient and well-tested, while remaining machine independent.
+ A few minor visible features have been added and/or changed.
+
+ * The `box' command in PlotFile is now simulated, whether or not
+ it is present in libplot.a
+
+ * The inlining-only-if-optimizing feature is still not fully implemented.
