+# Brief review of the jam language:
+#
+# Statements:
+# rule RULE - statements to process a rule
+# actions RULE - system commands to carry out target update
+#
+# Modifiers on actions:
+# together - multiple instances of same rule on target get executed
+# once with their sources ($(>)) concatenated
+# updated - refers to updated sources ($(>)) only
+# ignore - ignore return status of command
+# quietly - don't trace its execution unless verbose
+# piecemeal - iterate command each time with a small subset of $(>)
+# existing - refers to currently existing sources ($(>)) only
+# bind vars - subject to binding before expanding in actions
+#
+# Special rules:
+# ALWAYS - always build a target
+# DEPENDS - builds the dependency graph
+# ECHO - blurt out targets on stdout
+# EXIT - blurt out targets and exit
+# INCLUDES - marks sources as headers for target (a codependency)
+# NOCARE - don't panic if the target can't be built
+# NOUPDATE - create the target if needed but never update it
+# NOTFILE - ignore the timestamp of the target (it's not a file)
+# TEMPORARY - target need not be present if sources haven't changed
+#
+# Special variables set by jam:
+# $(<) - targets of a rule (to the left of the :)
+# $(>) - sources of a rule (to the right of the :)
+# $(xxx) - true on xxx (UNIX, VMS, NT, OS2, MAC)
+# $(OS) - name of OS - varies wildly
+# $(JAMVERSION) - version number (2.3)
+#
+# Special variables used by jam:
+# SEARCH - where to find something (used during binding and actions)
+# LOCATE - where to plop something not found with SEARCH
+# HDRRULE - rule to call to handle include files
+# HDRSCAN - egrep regex to extract include files
+#
+# Special targets:
+# all - default if none given on command line
+#
+
+# Initialize variables

+ * This wrapper is a workaround for a funny _popen() feature on Windows
+ * where it eats external quotes in some cases. The bug seems to be related
+ * to the quote stripping functionality used by the Windows cmd.exe
+ * interpreter when its /S is not specified.
+ *
+ * Cleaned up quote from the cmd.exe help screen as displayed on Windows XP
+ * SP3:
+ *
+ * 1. If all of the following conditions are met, then quote characters on
+ * the command line are preserved:
+ *
+ * - no /S switch
+ * - exactly two quote characters
+ * - no special characters between the two quote characters, where
+ * special is one of: &<>()@^|
+ * - there are one or more whitespace characters between the two quote
+ * characters
+ * - the string between the two quote characters is the name of an
+ * executable file.
+ *
+ * 2. Otherwise, old behavior is to see if the first character is a quote
+ * character and if so, strip the leading character and remove the last
+ * quote character on the command line, preserving any text after the
+ * last quote character.
+ *
+ * This causes some commands containing quotes not to be executed correctly.
+ * For example:
+ *
+ * "\Long folder name\aaa.exe" --name="Jurko" --no-surname
+ *
+ * would get its outermost quotes stripped and would be executed as:
+ *
+ * \Long folder name\aaa.exe" --name="Jurko --no-surname
+ *
+ * which would report an error about '\Long' not being a valid command.
+ *
+ * cmd.exe help seems to indicate it would be enough to add an extra space
+ * character in front of the command to avoid this but this does not work,
+ * most likely due to the shell first stripping all leading whitespace
+ * characters from the command.
+ *
+ * Solution implemented here is to quote the whole command in case it
+ * contains any quote characters. Note thought this will not work correctly
+ * should Windows ever 'fix' this feature.
+ * (03.06.2008.) (Jurko)

+Description: Build tool
+ Boost.Jam is a portable build tool with its own interpreted language, which
+ allows to implement rather complex logic in a readable way and without
+ resorting to external programs. It is a descendant of Jam/MR tool modified to
+ suit the needs of Boost.Build. In particular, modules and rule parameters
+ were added, as well as several new builtins.

+ <title>DESCRIPTION</title>
+
+ <para>Jam is a program construction tool, like make(1).</para>
+
+ <para>Jam recursively builds target files from source files, using
+ dependency information and updating actions expressed in the
+ Jambase file, which is written in jam's own interpreted language.
+ The default Jambase is compiled into jam and provides a
+ boilerplate for common use, relying on a user-provide file
+ "Jamfile" to enumerate actual targets and sources.</para>

+ * hcache() - return list of headers on target. Use cache or do a scan.

+ * Roughly, the modules are:

+ * compile.c - compile parsed jam statements
+ * execunix.c - execute a shell script on UNIX

+ * expand.c - expand a buffer, given variable values
+ * file*.c - scan directories and archives on *
+ * hash.c - simple in-memory hashing routines
+ * hdrmacro.c - handle header file parsing for filename macro definitions
+ * headers.c - handle #includes in source files
+ * jambase.c - compilable copy of Jambase
+ * jamgram.y - jam grammar
+ * lists.c - maintain lists of strings
+ * make.c - bring a target up to date, once rules are in place
+ * make1.c - execute command to bring targets up to date
+ * newstr.c - string manipulation routines
+ * option.c - command line option processing
+ * parse.c - make and destroy parse trees as driven by the parser
+ * path*.c - manipulate file names on *
+ * hash.c - simple in-memory hashing routines
+ * regexp.c - Henry Spencer's regexp
+ * rules.c - access to RULEs, TARGETs, and ACTIONs
+ * scan.c - the jam yacc scanner
+ * search.c - find a target along $(SEARCH) or $(LOCATE)
+ * timestamp.c - get the timestamp of a file or archive member
+ * variable.c - handle jam multi-element variables
+ *
+ * 05/04/94 (seiwald) - async multiprocess (-j) support
+ * 02/08/95 (seiwald) - -n implies -d2.

+/*
+ Independent implementation of MD5 (RFC 1321).
+
+ This code implements the MD5 Algorithm defined in RFC 1321, whose
+ text is available at
+ http://www.ietf.org/rfc/rfc1321.txt
+ The code is derived from the text of the RFC, including the test suite
+ (section A.5) but excluding the rest of Appendix A. It does not include
+ any code or documentation that is identified in the RFC as being
+ copyrighted.
+
+ The original and principal author of md5.c is L. Peter Deutsch
+ <ghost@aladdin.com>. Other authors are noted in the change history
+ that follows (in reverse chronological order):
+
+ 2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
+ either statically or dynamically; added missing #include <string.h>
+ in library.
+ 2002-03-11 lpd Corrected argument list for main(), and added int return
+ type, in test program and T value program.
+ 2002-02-21 lpd Added missing #include <stdio.h> in test program.
+ 2000-07-03 lpd Patched to eliminate warnings about "constant is
+ unsigned in ANSI C, signed in traditional"; made test program
+ self-checking.
+ 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
+ 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
+ 1999-05-03 lpd Original version.

+ Independent implementation of MD5 (RFC 1321).
+
+ This code implements the MD5 Algorithm defined in RFC 1321, whose
+ text is available at
+ http://www.ietf.org/rfc/rfc1321.txt
+ The code is derived from the text of the RFC, including the test suite
+ (section A.5) but excluding the rest of Appendix A. It does not include
+ any code or documentation that is identified in the RFC as being
+ copyrighted.
+
+ The original and principal author of md5.h is L. Peter Deutsch
+ <ghost@aladdin.com>. Other authors are noted in the change history
+ that follows (in reverse chronological order):
+
+ 2002-04-13 lpd Removed support for non-ANSI compilers; removed
+ references to Ghostscript; clarified derivation from RFC 1321;
+ now handles byte order either statically or dynamically.
+ 1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
+ 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
+ added conditionalization for C++ compilation from Martin
+ Purschke <purschke@bnl.gov>.
+ 1999-05-03 lpd Original version.
