-# Note: This makefile usese MinGW to produce native windows
-# libraries and executables.  The dll/import library, and
-# executable files will have the same names as those produced
-# using other Windows compilers, e.g. MSVC++.  So be aware that
-# there is no way to reliably distinguish between these two compiler
-# sources based on output filenames.
-
-# This will build EPANET as a native windows DLL and import
-# library (epanet2.dll/libepanet2.dll.a) using MinGW/gcc,
-# and a standalone executable (epanet2.exe).
-# This makefile also creates a windows batch file
-# (see MScmdname below) that can be run to produce an import
-# library for linking the DLL using MSVC.
-# This makefile assumes a minimum
-# MinGW installation, and uses the MinGW gcc compiler from
-# the MinGW install directory.
-# The current release of MinGW can be obtained from
-# http://www.mingw.org/wiki/Getting_Started -- the easiest
-# approach is to download the latest MingW installer and
-# accept all of the defaults.

-# The following targets are defined (for execution in
-# the build directory):

-#     -Builds epanet2.dll, epanet2.def, libepanet2.dll.a,
-#      epanet2.exe
-# make install
-#     -Creates scripts runepanet2.sh and CreateEpanet2Lib.bat that
-#      execute epanet2.exe, and MSVC 'lib' (to create an MSVC
-#      import library).  The runepanet2.sh wrapper simply exports
-#      environment variables so that the DLL is found at runtime,
-#      allowing you to specify your own locations for installing
-#      the DLL.
-#     -Installs epanet2.dll, epanet2.exe, and runepanet2.sh
-#      in <prefix>/bin, where <prefix> defaults to ~ (and can be set
-#      below to something different - see "Install directories")
-#     -Installs libepanet2.dll.a (import library), epanet2.def,
-#      and CreateEpanet2Lib.bat in <prefix>/lib
-#     -Installs epanet2.h in <prefix>/include.  This is the required
-#      header file for the EPANET programmer's toolkit, and thus
-#      <prefix>/include should be on your CPP include search path
-#      for subsequent use of the toolkit and linking with the import
-#      library libepanet2.dll.a or epanet2.lib.
-# make clean
-#     -Removes object and library files, returning the build directory

-Contents of EPANET2.ZIP
-=======================
-This archive contains the source code for the EPANET 2
-network hydraulic and water quality solver. The solver
-provides functions for simulating the extended period
-hydraulic and water quality behavior of water distribution
-system pipe networks. It is written in ANSI-compatible C
-and can be compiled into either a Windows Dynamic Link
-Library of functions or into a command-line executable.
-
-The archived code is set up for compilation as a DLL.
-To compile it as a command line (or console) application
-simply comment out the "#define DLL" macro statement at
-the top of EPANET.C and un-comment the "#define CLE" macro.
-
-The DLL version of the solver (epanet2.dll) is used with
-the EPANET 2 user interface executable (epanet2w.exe) to
-form a complete Windows modeling package. It also serves
-as the function library for the EPANET Programmer's Toolkit,
-allowing developers to construct their own customized pipe
-network analysis applications.
-
-The following C-code files are included in this archive:
-    EPANET.C  -- main module providing supervisory control
-    INPUT1.C  -- controls processing of input data
-    INPUT2.C  -- reads data from input file
-    INPUT3.C  -- parses individual lines of input data
-    INPFILE.C -- saves modified input data to a text file
-    RULES.C   -- implements rule-based control of piping system
-    HYDRAUL.C -- computes extended period hydraulic behavior
-    QUALITY.C -- tracks transport & fate of water quality
-    OUTPUT.C  -- handles transfer of data to and from binary files
-    REPORT.C  -- handles reporting of results to text file
-    SMATRIX.C -- sparse matrix linear equation solver routines
-    MEMPOOL.C -- memory pool management routines
-    HASH.C    -- hash table routines
-
-Also included are the following header files:
-    TOOLKIT.H  -- function prototypes of exported DLL functions
-    FUNCS.H    -- prototypes of all other functions
-    TYPES.H    -- declaration of global constants and data structures
-    VARS.H     -- declaration of global variables
-    HASH.H     -- header file for hash table routines

-Build 2.00.12 (2/25/08)
------------------------
-
-Computational Engine Changes (epanet2.dll and epanet2d.exe):
-===============================================================================
-CODE MODULES  CHANGES
-===============================================================================
-EPANET.C      Temporary files are now written to the users's current working
-INPUT1.C      directory or to the designated Temporary Directory when running
-VARS.H        the Windows GUI, thus avoiding file access problems for users
-FUNCS.H       who do not have administrative privileges on their machine.
--------------------------------------------------------------------------------
-EPANET.C      The following tank parameters were made available for retrieval
-TOOLKIT.H     using the Toolkit's ENgetnodevalue function: tank diameter,
-EPANET2.H     minimum volume, index of the tank's volume curve, the initial,
-              minimum, and maximum water levels, the fraction of a 2-compart-
-              ment tank devoted to the mixing zone, and the tank's bulk
-              reaction rate coefficient. These same parameters (with the
-              exception of the volume curve) were made modifiable using the
-              ENsetnodevalue function, as was the choice of mixing model.
-              See the Toolkit Help file for details.
--------------------------------------------------------------------------------
-EPANET.C      A new Toolkit function, ENaddpattern, was added that allows
-TOOLKIT.C     programmers to add a new time pattern to the network in any
-EPANET2.H     custom code that they write.
--------------------------------------------------------------------------------
-HYDRAUL.C     A DAMPLIMIT parameter was added to control at what point during
-INPUT1.C      the hydraulic solution iterations status checks on PRVs and PSVs
-INPUT3.C      begin and subsequent flow changes are dampened.
-REPORT.C
-VARS.H
-TEXT.H
--------------------------------------------------------------------------------
-HYDRAUL.C     Demands for tanks (net inflows/outflows) were not always being
-              set to zero when the tank was full or empty which was causing
-              problems in the water quality routing solutions.
--------------------------------------------------------------------------------
-QUALITY.C     The water quality functions for all of the tank mixing models
-              were modified so as to produce more robust results for cases
-              where there is a significant amount of volume exchange over a
-              water quality time step.
--------------------------------------------------------------------------------
-EPANET.C      A problem with the system not recognizing that water quality
-QUALITY.C     reactions could begin after some initial period of time when
-VARS.H        the Toolkit was used to modify reaction rate coefficients was
-              fixed.
--------------------------------------------------------------------------------
-INPFILE.C     A problem with extraneous lines being written to the [REPORT]
-              section of an EPANET input file created with the ENsaveinpfile
-              function was fixed. Also the number of decimal places for some
-	      items written to the saved file, such as nodal demands, was
-	      increased.
--------------------------------------------------------------------------------
-TYPES.H       The code version was changed to 20012 and INT4 was explicitly
-              defined as an "int" data type.
