2013/12/09
	+ updated configure script macros
	+ update config.guess, config.sub

2012/03/18
	+ add rpm script.
	+ fixes for DESTDIR in makefiles
	+ add cb++ script to install-rules
	+ integrate patch from Debian package, to search for bcpp.cfg in
	  user's home-directory and optionally a compile-time specific
	  directory.
	+ add dpkg script from Debian package, for testing.
	+ updated configure script macros
	+ drop mkdirs.sh, using "mkdir -p"
	+ update config.guess, config.sub

2009/06/30
	+ updated configure scripts
	+ improve exec-sql parser, detecting inline comments beginning with
	  "--".
	+ fix a case where multi-line indent was set during a #define, and
	  not reset on completion of the #define, causing the following code
	  to be indented.
	+ check for braces or preprocessor-level before indenting comments
	  which are on a line without code.
	+ improve config-file parser, which used strstr...
	+ add keep_code_with_comment option, to merge inline-comments with
	  the code immediately following, rather than merging (for example)
	  with trailing "}" (request by Daniel Lin).

2005/07/25
	+ add COPYING (request by Peter Hille).
	+ fixes for Intel 9.0 compiler-warnings.
	+ add AC_EXEEXT and AC_OBJEXT checks to configure properly with cygwin.

2005/05/16
	+ fixes to build with g++ 2.95.3
	+ add .SUFFIXES rule to build with Solaris make.

2005/04/10
	+ correct some regressions introduced by 2004/10/27:
	  + check if a line began as part of a quoted string string before
	    computing its indentation.
	  + count indent-level for curly-braces within #define's.
	+ improve configure check for g++ warnings (from ncurses).

2004/10/27
	+ correct logic that tracks state of preprocessor lines that continue
	  from one line to the next.  The additional lines were not marked
	  as preprocessor lines (report by Edward Bishop).
	+ updated configure script, fixes a check that added some gcc warning
	  options which are not recognized by g++.

2003/11/03
	+ correct one of the valgrind fixes from 2003/04/23 which used delete[]
	  in a special case where delete was correct (reports by Gert van de
	  Kraats <Gert.vandeKraats@getronics.com> and John Whitley
	  <JSWHITLEY@mail.dstl.gov.uk>).

2003/04/23
	+ fix several mismatches between new and delete (versus delete[])
	  reported by valgrind.
	+ add place_top_brace_on_new_line to config, with corresponding
	  command-line options -tbcl and tbnl to disable or enable it
	  respectively.  This is for the special case of the top-level
	  brace, e.g., at the function-level, to better match K&R style
	  braces (request by Daniel Lin).
	+ modified run-test script to facilitate testing variations of bcpp.cfg

2002/11/24
	+ check in OutputToOutFile() for a trailing C-comment fragment which
	  happened to precede code on the same line, e.g.,
		*/ a = b;
	  and split the line to avoid constructing
		a = b; */
	  (reports by Andreas Werner and Yanir Lubetkin
	  <yanir.lubetkin@emblaze.com>
	+ add isFinalComment() check to ensure that embedded comments are
	  not moved, e.g.,
		void myFunct(int /*number*/, float* /*data*/);
	  (report by Andreas Werner).

2002/11/23
	+ add a simple configure script.
	+ rename UNIX makefile to makefile.unx, changing compiler definition
	  from "gcc -x g++" to "g++", since that no longer works with gcc 3.2
	  (report by Don Park <don.park@beehivegames.com>).
	+ remove obsolete 'unix' subdirectory.

2002/05/18
	+ add indent_both_braces config-file option and corresponding
	  command-line -nbbi, -ybbi options to allow user to indent both
	  leading/trailing braces of a block by one level (adapted from patch
	  by Brad Mettee <bmettee@clark.net>).

	+ add brace_indent config-file option and corresponding command-line
	  -nbi, -ybi options to allow user to indent the trailing brace of a
	  block to align with its content rather than the beginning of the
	  block (detailed request by Edwin Robert Tisdale
	  <E.Robert.Tisdale@jpl.nasa.gov>)

	+ correct isContinuation() by ignoring backslash characters within
	  comments.  This makes it handle comment blocks such as 
		 /*******\
		  * BUG *
		 \*******/
	  (reported by Andreas Werner <werner@vircinity.com>).

	+ add makefile.blc for Borland C (from Chris Elliott <cje2@york.ac.uk>).

	+ remove references to obsolete email address <dickey@clark.net>

	+ add CHANGES file, document the sets of changes I marked in RCS

	+ add MANIFEST file.

1999/08/10
	+ makefile: do not link with -lg++ anymore

	+ makefile:  change $D to "./", to make vile follow the compiler
	  warnings more easily

	+ add __FILE__ to traceOutput() calls

	+ fixes to compile on SunOS 4.x, which needs the <string.h> stuff
	  prototyped also, change interface of traceInput() and traceOutput()
	  to add __FILE__

	+ fix a case Jeff Gilliat pointed out - an inline C comment fragment
	  resulted in commenting out the code on that line.

	+ mods in IndentNonBraces() which serve to distinguish "public:" which
	  is a class scope from "public" which is a Java type.  Otherwise we
	  get odd indention for the latter case.

	+ backup.cpp: had allocated one char too few for ".orig" suffix

1999/01/21
	+ rename the backup file to .orig, since "~" confuses WinNT's directory
	  scanning, making it return the same file more than once.

	+ open the output in binary mode, so we get ^J's rather than ^M^J's

1999/01/04
	+ kludge to ifdef for g++ versus M$ Visual C++

	+ kludge to compile in case we have the misfortune to use gcc 2.8.1
	  with Solaris's header files (some idiot decided to undef __STDC__ in
	  g++ because they disapprove of using __STDC__ for ifdef'ing).

	+ change defaults in bcpp.cfg to use_tabs=yes, and
	  comments_with_code=33 (the original bpp.cfg is in top-level).

	+ baseq.cpp:  fix so we do not try to peek into a negative index

	+ add top-level bcpp.cfg, indent.bat, indent.cfg as part of port to
	  win32.

	+ add txtdocs/manual.txt to distribution, updated wpdocs/manual.doc

1999/01/02
	+ mods to "work" with tisca.h, which contains a number of comments
	  within long multi-line comments.  This isn't quite right, since lines
	  containing only a backslash are deleted, where they should be
	  combined just like blank lines.

	+ add run-test file (used with regression test-cases not part of the
	  distribution).

	+ implement html.cpp, to provide limited support for indenting
	  JavaScript embedded in HTML files.

	+ split-out backup.cpp to support renaming of the original file,
	  preserving its modification-time, to allow recovery if the indent is
	  not needed (makes no change), or otherwise should be discarded.

	+ implement verbose.cpp, to support interactions such as stopping
	  processing a set of files on an error.

	+ change scattered printf's to call verbose(), and fprintf(stderr's to
	  warning().

	+ rewrote ReadLine so it doesn't use fseek/ftell (which is a porting
	  problem).

	+ config.cpp:  removed a lot of ugly/repetitious code

	+ config.cpp:  moved ShowConfig here from bcpp.cpp

	+ debug.cpp:  change trace() calls to not use stderr explicitly.

1997/04/04
	+ first draft of logic to reset indent-stack at the end of a multi-line
	  preprocessor command.  also, fixed (?) a bug in splitting
	  continuation-line (but there's more)

	+ allow unrecognized preprocessor-lines to be indented

	+ refine a change to allow for things like "else return;"

	+ replaced a couple of strcmp calls by CompareKeyword to allow for
	  matching both "else" and "else if" statements.

	+ fixes for places where we split a line that has continuation-marker
	  on the end.  while I was at it, trim redundant whitespace before the
	  '\', to make it uniform.

1997/01/07
	+ tabs.cpp:  fix a place where I trimmed trailing blanks from data w/o
	  trimming state, causing bogus results with baseobj.hh, due to overrun
	  in later logic.

	+ lots of spelling corrections.

	+ fixes for stricter gcc warnings

1996/12/24
	+ updated copyright notices.

	+ refined adjustment of inline comments to work with hanging.cpp, which
	  doesn't take that into account.

	+ remove unused logic for adjustHangingComment, since I'm doing this in
	  a different way.

1996/12/17
	+ execsql.cpp:  refined hanging-indents to account for statements other
	  than the two block-styles we use

	+ make SqlStruct a class

1996/12/12
	+ shift-adjust dangling else{} block

	+ makefile:  record the debug-ifdefs

	+ hanging.cpp:  make HangStruct class to get rid of static variables

	+ bcpp.h:  made HangStruct class

	+ change hang_state from an int to a class

	+ made singleIndentLen obsolete via hanging.cpp

1996/12/06
	+ tabs.cpp:  mods to allow tabs in OutputStruct.filler

	+ fix a few leaks

	+ ensure that hanging comments remain hanging when re-indenting.

	+ use tabs for OutputStruct.filler

1996/12/05
	+ tabs.cpp:  correct leading-whitespace conversion (space is printable
	  ;-)

	+ hanging.cpp:  remove redundant reset of hang_state

	+ debug.cpp:  SunOS 4.x needs stdlib.h for size_t

	+ add InputStruct.offset

	+ add OutputStruct.splitElseIf

	+ remove IndentStruct.firstPass, because hanging.cpp does it better

	+ mods to preserve code-fragment's offset to use in shifting
	  block-indented C-style comments

	+ fixes for offset adjustment due to stripping whitespace from
	  fragments in DecodeLine

	+ first cut of logic to pass offset of code-fragments into InputStruct
	  (to use for categorizing hanging comments)

	+ revised logic for split else/if statement using flag 'splitElseIf'. 
	  this fixes the problem of indenting the code undef 'if'.

	+ mods to make TestLineHasCode look at the parse-state (which is more
	  reliable)

	+ remove IndentStruct.firstPass logic, since hanging.cpp does it better

	+ add pBFlag to OutputStruct to use in hanging.cpp

1996/11/15
	+ tabs.cpp:  correct off-by-one in return from skipEscape() that ate
	  trailing quote.

	+ bcpp.h:  rename OutputStruct.pState to OutputStruct.pCFlag

	+ bcpp.h:  add OutputStruct.pBFlag

	+ use OutputStruct.indentHangs

	+ split-out hanging.cpp

	+ hanging.cpp:  add 'do_aggreg' flag

	+ hanging.cpp:  use new member of OutputStruct, indentHangs to allow
	  merge with info from execsql.cpp

1996/11/08
	+ move emptyString to bcpp.h

	+ pass-in Config struct to IndentSQL, making it pass by ref everywhere

	+ move some string-parsing to strings.cpp, to re-use in execsql.cpp

	+ move debug/trace code to debug.cpp

	+ move input/output/indent definitions to bcpp.h

	+ align successive else/if

	+ don't set interfunction-spacing for lines that happen to have R_CURL,
	  if there's more on the line.

	+ add indent_exec_sql to bcpp.cfg

	+ execsql.cpp - quick hack to indent non-keyword stuff extra

	+ move some functions to strings.cpp from bcpp.cpp, for use in
	  execsql.cpp

1996/11/06
	+ restructured keyword-lookup to add 3rd type (blockLine).  use this to
	  fix case (successive lines) with "while", "switch" -- the
	  curly-braces for "switch" weren't indented under "switch".

	+ also, dropped special logic for singleIndentLen, making it the same
	  as a standard indent (was too ugly).

1996/11/05
	+ propagate parse-state via InputStruct to OutputStruct.

	+ correct potential indention of continued-string fragments.

1996/11/04
	+ moved string-table to config.cpp

	+ fix uninitialized-memory-ref (Purify)

	+ unused parameter.

	+ add indent_preprocessor

	+ simplify config.cpp a little using overloading

	+ corrected some minor bugs affecting indention

	+ add "#else" to typeOfPreP(), along with all other standard
	  directives.

	+ use enum rather than int for 'attrib' types.  change name of one
	  'attrib' type to make it easier to maintain.  fixes for TRACE.

	+ first cut of indent_preprocessor option

	+ modify so that both comma and semicolon are treated specially after
	  '}', to make data lists work properly

	+ correct a couple of special cases with multi-indent

1996/10/31
	+ fixes for memory leaks

	+ corrections to tab computation

	+ add special state for '#' pre-processor lines

	+ makefile - move some symbols to accommodate non-g++

	+ add POUNDC

	+ mods to track preprocessor-lines

	+ reduce ConstructLine to a single-level switch, rather than the nested
	  one that will get in the way of mods for execsql

	+ refined logic in dontHangComment(), fixing a case I missed before.

	+ correct a logical-reduction for matching against PreP types

	+ suppress inter-function spacing before "#endif"

	+ add pType to OutputStruct so I can tag them as PreP when needed

	+ fix while-loop that was expressed as for-loop with break

	+ undid unnecessary if-level in ConstructLine

	+ restore leading tabs in comments if we're expanding tabs

	+ moved the non-printing character conversion to tabs.cpp

1996/10/20
	+ moved delete for lineState into  bcpp.cpp

	+ make pString in/out for ExpandTabs

	+ modify ExpandTabs to maintain a string of CharState values

	+ corrected state: allow tab-expansion in // comments

	+ add strings.cpp

	+ make pString in/out for ExpandTabs

	+ fixes for include-order (bcpp.h should be last)

	+ reduce FindStartofComment and FindEndofComment to return index
	  instead of pointers

	+ revised FindPunctuation so it returns an index rather than a pointer,
	  and uses the pLineState info so that we can easily discard quoted
	  punctuation (which didn't work for a complicated string, e.g.,
	  "'\\0','\\0'}").

	+ changed allocation scheme of lineState

	+ drop CComments param of DecodeLine, since pLineState contains proper
	  info

	+ fixes for blank-lines:  ensure that we don't emit trailing
	  blank-lines in a file, that except for inter-function blanks, we
	  reduce runs of blank lines to a single blank, and that there's no
	  lines (even comments) that come out with trailing whitespace.

	+ simplify allocation/deallocation in DecodeLine by leaving pLineData
	  alone.

	+ a couple of Purify-fixes

	+ modify ExpandTabs to maintain a string of CharState values; use this
	  to retain parsing state so I can correct blank-trimming (so that
	  continuation lines of a string aren't trimmed!).

1996/10/12
	+ split-out bcpp.h and tabs.cpp

	+ moved tab-expansion (and tab-spacing) into separate file, first to
	  fix an error in tab-expansion (wrong fill amount), then to allow
	  rewrite to capture left/right CharState, to prevent quoted tabs from
	  being expanded.  Also, moved L_CURL, R_CURL, DQUOTE, SQUOTE into
	  config.h, making capitalization consistent.

	+ fixes for multi-line C comments

	+ implement shiftToMatchSingleIndent, peekIndexOfBrace,
	  chainedSingleIndent

	+ better logic in resetSingleIndent(), to reset all pending
	  single-indents

	+ ifdef'd trace code so I don't have to uncomment it added clause in
	  IndentNonBraceCode to (try to) reset singleIndentLen immediately
	  after "{" -- works in one place but not another

	+ eliminate single-char constant-strings to use strchr instead of
	  strstr.  use FindPunctuation to simplify some logic

	+ new function CompareKeyword fixes parse ambiguity with strstr allow
	  combination of tabs and spaces.
