+
+# The Kitware System Library is intended to be included in other
+# projects.  It is completely configurable in that the library's
+# namespace can be configured and the components that are included can
+# be selected invididually.
+
+# Typical usage is to import the kwsys directory tree into a
+# subdirectory under a parent project and enable the classes that will
+# be used.  All classes are disabled by default.  The CMake listfile
+# above this one configures the library as follows:
+#
+#  SET(KWSYS_NAMESPACE foosys)
+#  SET(KWSYS_USE_Directory 1)    # Enable Directory class.
+#  SUBDIRS(kwsys)
+#
+# Optional settings are as follows:
+#
+#  KWSYS_HEADER_ROOT = The directory into which to generate the kwsys headers.
+#                      A directory called "${KWSYS_NAMESPACE}" will be
+#                      created under this root directory to hold the files.
+#
+#    Example:
+#
+#      SET(KWSYS_HEADER_ROOT ${PROJECT_BINARY_DIR})
+#      INCLUDE_DIRECTORIES(${PROJECT_BINARY_DIR})
+#
+#  KWSYS_IOS_FORCE_OLD = Force use of old non-ANSI C++ streams even if
+#                        new streams are available.  This may be used
+#                        by projects that cannot configure their
+#                        streams library.
+#    Example:
+#
+#      SET(KWSYS_IOS_FORCE_OLD 1)
+#
+#
+# Optional settings to setup install rules are as follows:
+#
+#  KWSYS_INSTALL_BIN_DIR     = The installation target directories into
+#  KWSYS_INSTALL_LIB_DIR       which the libraries and headers from
+#  KWSYS_INSTALL_INCLUDE_DIR   kwsys should be installed by a "make install".
+#                              The values should be specified relative to
+#                              the installation prefix and NOT start with '/'.
+#  KWSYS_INSTALL_DOC_DIR     = The installation target directory for documentation
+#                              such as copyright information.
+#
+#  KWSYS_INSTALL_COMPONENT_NAME_RUNTIME     = Name of runtime and development
+#  KWSYS_INSTALL_COMPONENT_NAME_DEVELOPMENT   installation components.
+#                                             If not given the install rules
+#                                             will not be in any component.
+#
+#  KWSYS_INSTALL_EXPORT_NAME = The EXPORT option value for install(TARGETS) calls.
+#
+#    Example:
+#
+#      SET(KWSYS_INSTALL_BIN_DIR bin)
+#      SET(KWSYS_INSTALL_LIB_DIR lib)
+#      SET(KWSYS_INSTALL_INCLUDE_DIR include)
+#      SET(KWSYS_INSTALL_COMPONENT_NAME_RUNTIME Runtime)
+#      SET(KWSYS_INSTALL_COMPONENT_NAME_DEVELOPMENT Development)
+
+# Once configured, kwsys should be used as follows from C or C++ code:
+#

+/** \class CommandLineArguments
+ * \brief Command line arguments processing code.
+ *
+ * Find specified arguments with optional options and execute specified methods
+ * or set given variables.
+ *
+ * The two interfaces it knows are callback based and variable based. For
+ * callback based, you have to register callback for particular argument using
+ * AddCallback method. When that argument is passed, the callback will be
+ * called with argument, value, and call data. For boolean (NO_ARGUMENT)
+ * arguments, the value is "1". If the callback returns 0 the argument parsing
+ * will stop with an error.
+ *
+ * For the variable interface you associate variable with each argument. When
+ * the argument is specified, the variable is set to the specified value casted
+ * to the apropriate type. For boolean (NO_ARGUMENT), the value is "1".
+ *
+ * Both interfaces can be used at the same time. 
+ *
+ * Possible argument types are:
+ *   NO_ARGUMENT     - The argument takes no value             : --A
+ *   CONCAT_ARGUMENT - The argument takes value after no space : --Aval
+ *   SPACE_ARGUMENT  - The argument takes value after space    : --A val 
+ *   EQUAL_ARGUMENT  - The argument takes value after equal    : --A=val
+ *   MULTI_ARGUMENT  - The argument takes values after space   : --A val1 val2 val3 ...
+ *
+ * Example use:
+ *
+ * kwsys::CommandLineArguments arg;
+ * arg.Initialize(argc, argv);
+ * typedef kwsys::CommandLineArguments argT;
+ * arg.AddArgument("--something", argT::EQUAL_ARGUMENT, &some_variable, 
+ *                 "This is help string for --something");
+ * if ( !arg.Parse() )
+ *   {
+ *   kwsys_ios::cerr << "Problem parsing arguments" << kwsys_ios::endl;
+ *   res = 1;
+ *   }

+  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.

+Implementation for Windows
+
+On windows, a thread is created to wait for data on each pipe.  The
+threads are synchronized with the main thread to simulate the use of
+a UNIX-style select system call.
+
+On Windows9x platforms, a small WIN32 console application is spawned
+in-between the calling process and the actual child to be executed.
+This is to work-around a problem with connecting pipes from WIN16
+console applications to WIN32 applications.

+KWSys provides a platform-independent API to many common system
+features that are implemented differently on every platform.  This
+library is intended to be shared among many projects, so it has a
+configurable namespace.  Each project should configure KWSys to use a
+namespace unique to itself.  See comments in CMakeLists.txt for
+details.
+
+You are probably reading this file in the source tree of a surrounding
+project.  In that case, see "../README.kwsys" for details of using
+KWSys in your project.

+/** \class RegularExpression
+ * \brief Implements pattern matching with regular expressions.
+ *
+ * This is the header file for the regular expression class.  An object of
+ * this class contains a regular expression, in a special "compiled" format.
+ * This compiled format consists of several slots all kept as the objects
+ * private data.  The RegularExpression class provides a convenient way to
+ * represent regular expressions.  It makes it easy to search for the same
+ * regular expression in many different strings without having to compile a
+ * string to regular expression format more than necessary.
+ *
+ * This class implements pattern matching via regular expressions.
+ * A regular expression allows a programmer to specify  complex
+ * patterns  that  can  be searched for and matched against the
+ * character string of a string object. In its simplest form, a
+ * regular  expression  is  a  sequence  of  characters used to
+ * search for exact character matches. However, many times  the
+ * exact  sequence to be found is not known, or only a match at
+ * the beginning or end of a string is desired. The RegularExpression regu-
+ * lar  expression  class implements regular expression pattern
+ * matching as is found and implemented in many  UNIX  commands
+ * and utilities.
+ *
+ * Example: The perl code
+ * 
+ *    $filename =~ m"([a-z]+)\.cc";
+ *    print $1;
+ *    
+ * Is written as follows in C++
+ *
+ *    RegularExpression re("([a-z]+)\\.cc");
+ *    re.find(filename);
+ *    cerr << re.match(1);
+ *
+ *
+ * The regular expression class provides a convenient mechanism
+ * for  specifying  and  manipulating  regular expressions. The
+ * regular expression object allows specification of such  pat-
+ * terns  by using the following regular expression metacharac-
+ * ters:
+ *
+ *  ^        Matches at beginning of a line
+ *
+ *  $        Matches at end of a line
+ *
+ * .         Matches any single character
+ *
+ * [ ]       Matches any character(s) inside the brackets
+ *
+ * [^ ]      Matches any character(s) not inside the brackets
+ *
+ *  -        Matches any character in range on either side of a dash
+ *
+ *  *        Matches preceding pattern zero or more times
+ *
+ *  +        Matches preceding pattern one or more times
+ *
+ *  ?        Matches preceding pattern zero or once only
+ *
+ * ()        Saves a matched expression and uses it in a  later match
+ *
+ * Note that more than one of these metacharacters can be  used
+ * in  a  single  regular expression in order to create complex
+ * search patterns. For example, the pattern [^ab1-9]  says  to
+ * match  any  character  sequence that does not begin with the
+ * characters "ab"  followed  by  numbers  in  the  series  one
+ * through nine.
+ *
+ * There are three constructors for RegularExpression.  One just creates an
+ * empty RegularExpression object.  Another creates a RegularExpression
+ * object and initializes it with a regular expression that is given in the
+ * form of a char*.  The third takes a reference to a RegularExpression
+ * object as an argument and creates an object initialized with the
+ * information from the given RegularExpression object.
+ *
+ * The  find  member function  finds   the  first  occurence   of  the regualr
+ * expression of that object in the string given to find as an argument.  Find
+ * returns a boolean, and  if true,  mutates  the private  data appropriately.
+ * Find sets pointers to the beginning and end of  the thing last  found, they
+ * are pointers into the actual string  that was searched.   The start and end
+ * member functions return indicies  into the searched string that  correspond
+ * to the beginning   and  end pointers  respectively.   The    compile member
+ * function takes a char* and puts the  compiled version of the char* argument
+ * into the object's private data fields.  The == and  != operators only check
+ * the  to see  if   the compiled  regular  expression   is the same, and  the
+ * deep_equal functions also checks  to see if the  start and end pointers are
+ * the same.  The is_valid  function returns false if  program is set to NULL,
+ * (i.e. there is no valid compiled exression).  The set_invalid function sets
+ * the  program to NULL  (Warning: this deletes the compiled  expression). The
+ * following examples may help clarify regular expression usage:
+ *
+ *   *  The regular expression  "^hello" matches  a "hello"  only at  the
+ *      beginning of a  line.  It would match "hello  there" but not "hi,
+ *      hello there".
+ *
+ *   *  The regular expression "long$" matches a  "long"  only at the end
+ *      of a line. It would match "so long\0", but not "long ago".
+ *
+ *   *  The regular expression "t..t..g"  will match anything that  has a
+ *      "t" then any two characters, another "t", any  two characters and
+ *      then a "g".   It will match  "testing", or "test again" but would
+ *      not match "toasting"
+ *
+ *   *  The regular  expression "[1-9ab]" matches any  number one through
+ *      nine, and the characters  "a" and  "b".  It would match "hello 1"
+ *      or "begin", but would not match "no-match".
+ *
+ *   *  The  regular expression "[^1-9ab]"  matches any character that is
+ *      not a number one  through nine, or  an "a" or "b".   It would NOT
+ *      match "hello 1" or "begin", but would match "no-match".
+ *
+ *   *  The regular expression "br* " matches  something that begins with
+ *      a "b", is followed by zero or more "r"s, and ends in a space.  It
+ *      would match "brrrrr ", and "b ", but would not match "brrh ".
+ *
+ *   *  The regular expression "br+ " matches something  that begins with
+ *      a "b", is followed by one or more "r"s, and ends in  a space.  It
+ *      would match "brrrrr ",  and  "br ", but would not  match "b  " or
+ *      "brrh ".
+ *
+ *   *  The regular expression "br? " matches  something that begins with
+ *      a "b", is followed by zero or one "r"s, and ends in  a space.  It
+ *      would  match  "br ", and "b  ", but would not match  "brrrr "  or
+ *      "brrh ".
+ *
+ *   *  The regular expression "(..p)b" matches  something ending with pb
+ *      and beginning with whatever the two characters before the first p
+ *      encounterd in the line were.  It would find  "repb" in "rep drepa
+ *      qrepb".  The regular expression "(..p)a"  would find "repa qrepb"
+ *      in "rep drepa qrepb"
+ *
+ *   *  The regular expression "d(..p)" matches something ending  with p,
+ *      beginning with d, and having  two characters  in between that are
+ *      the same as the two characters before  the first p  encounterd in
+ *      the line.  It would match "drepa qrepb" in "rep drepa qrepb".

+
+  Specify search and executable paths relative to the forwarding
+  executable location or as full paths.  Include no trailing slash.
+  In the case of a multi-configuration build, when CMAKE_INTDIR is

+  the executable (the one containing the per-configuration
+  subdirectory specified by CMAKE_INTDIR).  Then PATH_BUILD entries

+  CMAKE_INTDIR as necessary.  In the above example imagine appending
+  the PATH_BUILD or EXE_BUILD setting to the DIR_BUILD setting.  The
+  result should form a valid path with per-configuration subdirectory.
+
+  Additional paths may be specified in the PATH_BUILD and PATH_INSTALL
+  variables by using comma-separated strings.    For example:
+
+  #define @KWSYS_NAMESPACE@_SHARED_FORWARD_PATH_BUILD \

+Allowing make variable replacements opens a can of worms.  Sometimes
+they should be quoted and sometimes not.  Sometimes their replacement
+values are already quoted or contain escapes.
+
+Some Visual Studio variables cause problems.  In order to pass the
+referenced value with spaces the reference must be quoted.  If the
+variable value ends in a backslash then it will escape the ending
+quote!  In order to make the ending backslash appear we need this:
+
+  "$(InputDir)\"
+
+However if there is not a trailing backslash then this will put a
+quote in the value so we need:
+
+  "$(InputDir)"
+
+This macro decides whether we quote an argument just because it
+contains a make variable reference.  This should be replaced with a
+flag later when we understand applications of this better.
