+# under the conditions detailed in the GNU General Public License (GPL). See 
+# the file COPYING for more information.
+#
+# This script compiles and/or links one or more source or object files into a
+# object file or executable target, and outputs all extra dependencies found
+# while doing so in a file named target.d, which can be used by GNU Make.
+#
+# The script should be invoked the same way as your C compiler, that is,
+# specifying the target using a -o option and the source or object files as 
+# non-option arguments. It will generate dependencies in the form
+#
+# target target.d: dir/file1.c dir/file2.c header1.h header2.h
+# dir/file1.c dir/file2.c header1.h header2.h:
+#
+# This version is intended for GCC, which can do compilation and dependency

+# overridden using the CC environment variable.
+#
+# CHANGELOG
+#
+# 2003/1/8: EvB: adapted for gcc 3.2, still handles 2.95 as well.
+#
+#   This was necessary because gcc 3.2 handles -MD differently than gcc 2.95:
+#   where the old version generated a .d file for each source, in the current
+#   directory, the new one does almost completely what this script intended to
+#   do: generate one .d file in the same directory and with the same file name
+#   as the target.
+#
+#   The only fixups 3.2's .d files still need are:
+#
+#   - changing the file name; gcc 3.2 strips the suffix of the target before 
+#     appending the .d, so targets x and x.o will both produce x.d, which is
+#     not what we want;
+#
+#   - adding the implicit dependencies as prerequisiteless targets, so that
+#     make will just consider the target out of date if one does not exist
+#     anymore; 
+#
+#   - adding the .d file as depending on the same prerequisites as our real
+#     target so that it will be considered out of date if one of the files
+#     mentioned in it are updated or missing.
+#
+#   Basically, this version does all that by simply including the file
+#   <strippedtarget>.d file in the list of .d files we look for. We may end
+#   up generating the same file name, but that already was handled correctly.
+#   Otherwise we perform the normal routine, so that we /know/ the targets will
+#   be correct, directories and all, regardless of variations in gcc behaviour.

+# This script installs zero or more files into a specified directory. If one or
+# more components of the destination path do not exist, they are created.  The

+# It is intended to replace the /usr/bin/install command, which has no portable

+# install arguments...
+#
+# Each argument is either an option, as specified below, a source file, or
+# a destination directory, with -d prepended. Each time a destination
+# directory is encountered, the source files leading up to it are installed,
+# and then all options are reset, allowing you to perform multiple install
+# operations with one command.
+#
+# Options:
+#
+#      -h      Show a brief usage message
+#      -v      Show what's being done
+#      -m      specify mode of destination files

+# * If multiple different modes are desired for files in a single destination

+# * The /bin/sh shell used to run this script must support user-defined

+# * The system must have mkdir, chmod, basename, tr, sed and cp available.

+# Notes (not bugs, features. Really!):
+#
+# * If the destination directory already exists, its mode is not changed
+#   even if -md is specified; that mode is only used when creating new ones.
+# * If the destination file already exists but is overwritten because no -n

+# * QNX-style paths starting with // are honored, as are .. path components.
+#   An initial .. works as expected, and a destination path a/b/../c creates

+To build the STLplus3 library collection, use the project files supplied at\r

+\r
+//   A smart pointer is a memory-managing pointer to an object. If you like, it\r
+//   is a zero-dimensional container.\r
+\r
+//   Assignment of smart pointers result in multiple aliases of the same object.\r
+//   The term alias is used to differentiate from conventional pointers because\r
+//   the semantics are different.\r
+\r
+//   Aliases can be turned into copies if the pointed-to class supports copying.\r
+\r
+//   These simple_ptr classes from DJDM have slightly different semantics than\r
+//   the smart_ptr classes of AJR. There are no cross-pointer side effects\r
+//   that occur when the pointer is cleared. The clear() function is effectively\r
+//   equivalent to the clear_unique() function of the smart_ptr. The only way\r
+//   that a "referenced" object will be deleted is if all simple_ptr's that\r
+//   reference the object are cleared (by deletion, manual clearing or reassignment).\r
+\r
+//   Also, the simple pointer cannot contain a reference to a shared null pointer\r
+//   (which occurs as a side-effect of clearing a multiply referenced object in\r
+//   the smart_ptr classes). Which means that if you have a null simple_ptr, then\r
+//   the assignment of any other null simple_ptr will NOT reassign the reference of\r
+//   any other simple_ptr. Hence, the simple_ptr class acts a little more like a\r
+//   normal pointer (with fewer side effects), with the added bonus of containment.\r
+\r
+//   Due to the way that the simple_ptr contains the data, it also allows the\r
+//   addition of various casting functions, while still keeping the managed data\r
+//   containment functionality of the underlying object. This means that you can\r
+//   have two simple_ptr's of different template types, both pointing to the same\r
+//   data (if the differing template types are derivatives of each other).\r
+\r
+//   The base class is simple_ptr_base which defines the common interface. Then\r
+//   there are three subclasses which have the same interface but different copy\r
+//   semantics:\r
+\r
+//   - simple_ptr        for simple types and classes which have copy constructors\r
+//   - simple_ptr_clone  for polymorphic class hierarchies which are copied using a clone method\r
+//   - simple_ptr_nocopy for any class that cannot or should not be copied\r

+//   Provides an sprintf-like function acting on STL strings. The 'd' in dprintf\r

+//   buffer would be static (in size that is, not static in C terms).\r
+\r
+//   The obvious solution to the problem of in-memory formatted output is to use\r

+//   should *never* be used and should be made obsolete.\r
+\r
+//   In any case, using arbitrary-sized fixed-length buffers is not part of any\r

+//   The integer is represented as a sequence of bytes. They are stored such that\r
+//   element 0 is the lsB, which makes sense when seen as an integer offset but\r
+//   is counter-intuitive when you think that a string is usually read from left\r
+//   to right, 0 to size-1, in which case the lsB is on the *left*.\r
+\r
+//   This solution is compatible with 32-bit and 64-bit machines with either\r
+//   little-endian or big-endian representations of integers.\r
+\r
+//   Problem: I'm using std::string, which is an array of char. However, char is\r
+//   not well-defined - it could be signed or unsigned.\r
+\r
+//   In fact, there's no requirement for a char to even be one byte - it can be\r
+//   any size of one byte or more. However, it's just impossible to make any\r
+//   progress with that naffness (thanks to the C non-standardisation committee)\r
+//   and the practice is that char on every platform/compiler I've ever come\r
+//   across is that char = byte.\r
+\r
+//   The algorithms here use unsigned char to represent bit-patterns so I have to\r
+//   be careful to type-cast from char to unsigned char a lot. I use a typedef to\r

+//   An infinite-precision integer class. This allows calculations on large\r
+//   integers to be performed without overflow.\r
+\r
+//   this class can throw the following exceptions:\r
+//     std::out_of_range\r
+//     std::overflow_error\r
+//     std::invalid_argument\r
+//     stlplus::divide_by_zero    // why doesn't std have this?\r
+//   all of these are derivations of the baseclass:\r
+//     std::logic_error\r
+//   So you can catch all of them by catching the baseclass\r
+\r
+//   Warning: inf was never intended to be fast, it is just for programs which\r
+//   need a bit of infinite-precision integer arithmetic. For high-performance\r
+//   processing, use the Gnu Multi-Precision (GMP) library. The inf type is just\r
+//   easier to integrate and is already ported to all platforms and compilers\r
+//   that STLplus is ported to.\r
