+-->
+<!-- A "project" describes a set of targets that may be requested
+ when Ant is executed. The "default" attribute defines the
+ target which is executed if no specific target is requested,
+ and the "basedir" attribute defines the current working directory
+ from which Ant executes the requested task. This is normally
+ set to the current working directory.
+-->
+ <project basedir=".." default="dist" name="proj4js">
+
+<!-- ===================== Property Definitions =========================== -->
+<!--
+ Each of the following properties are used in the build script.
+ Values for these properties are set by the first place they are
+ defined, from the following list:
+
+ * Definitions on the "ant" command line (ant -Dfoo=bar compile).
+
+ * Definitions from a "build.properties" file in the top level
+ source directory of this application.
+
+ * Definitions from a "build.properties" file in the developer's
+ home directory.
+
+ * Default definitions in this build.xml file.
+
+ You will note below that property values can be composed based on the
+ contents of previously defined properties. This is a powerful technique
+ that helps you minimize the number of changes required when your development
+ environment is modified. Note that property composition is allowed within
+ "build.properties" files as well as in the "build.xml" script.

+
+<!-- ==================== File and Directory Names ======================== -->
+<!--
+
+ These properties generally define file and directory names (or paths) that
+ affect where the build process stores its outputs.
+
+ app.name Base name of this application, used to
+ construct filenames and directories.
+ Defaults to "myapp".
+
+ app.path Context path to which this application should be
+ deployed (defaults to "/" plus the value of the
+ "app.name" property).
+
+ app.version Version number of this iteration of the application.
+
+ build.home The directory into which the "prepare" and
+ "compile" targets will generate their output.
+ Defaults to "build".
+
+ dist.home The name of the base directory in which
+ distribution files are created.
+ Defaults to "dist".

+ <property name="dist.home" value="${basedir}/dist"/>
+ <property name="docs.home" value="${build.home}/docs"/>
+
+
+<!-- ==================== Prepare Target ================================== -->
+<!--
+ The "prepare" target is used to create the "build" destination directory,
+ and copy the static contents of your web application to it. If you need
+ to copy static files from external dependencies, you can customize the
+ contents of this task.
+
+ Normally, this task is executed indirectly when needed.

+ </copy>
+ </target>
+
+
+<!-- ==================== Clean Target ==================================== -->
+<!--
+
+ The "clean" target deletes any previous "build" and "dist" directory,
+ so that you can be ensured the application can be built from scratch.
+
+-->
+
+ <target description="Delete old build and dist directories" name="clean">

+ environment.

+This is a JavaScript library that provides methods for coordinate
+transformations between map projections and longitude/latitude,
+including datum transformations, in a web client.
+ </p>
+
+ <p>
+To use the Proj4js, you first create a source and destination Proj4js.Proj
+objects, passing in a projection code (e.g. EPSG:4326).
+You can then use the Proj4js.transform() method, passing in map XY as a point
+object and the source and destination projection objects,
+and it returns the point coordinate in the destination projection.

+/**
+ * Namespace: Proj4js
+ *
+ * Proj4js is a JavaScript library to transform point coordinates from one
+ * coordinate system to another, including datum transformations.
+ *
+ * This library is a port of both the Proj.4 and GCTCP C libraries to JavaScript.
+ * Enabling these transformations in the browser allows geographic data stored
+ * in different projections to be combined in browser-based web mapping
+ * applications.
+ *
+ * Proj4js must have access to coordinate system initialization strings (which
+ * are the same as for PROJ.4 command line). Thes can be included in your
+ * application using a <script> tag or Proj4js can load CS initialization
+ * strings from a local directory or a web service such as spatialreference.org.
+ *
+ * Similarly, Proj4js must have access to projection transform code. These can
+ * be included individually using a <script> tag in your page, built into a
+ * custom build of Proj4js or loaded dynamically at run-time. Using the
+ * -combined and -compressed versions of Proj4js includes all projection class
+ * code by default.
+ *
+ * Note that dynamic loading of defs and code happens ascynchrously, check the
+ * Proj.readyToUse flag before using the Proj object. If the defs and code
+ * required by your application are loaded through script tags, dynamic loading
+ * is not required and the Proj object will be readyToUse on return from the
+ * constructor.
+ *
+ * All coordinates are handled as points which have a .x and a .y property
+ * which will be modified in place.
+ *
+ * Override Proj4js.reportError for output of alerts and warnings.
+ *
+ * See http://trac.osgeo.org/proj4js/wiki/UserGuide for full details.

+NAME NEW ZEALAND MAP GRID
+
+PURPOSE: Transforms input longitude and latitude to Easting and
+ Northing for the New Zealand Map Grid projection. The
+ longitude and latitude must be in radians. The Easting
+ and Northing values will be returned in meters.
+
+
+ALGORITHM REFERENCES
+
+1. Department of Land and Survey Technical Circular 1973/32
+ http://www.linz.govt.nz/docs/miscellaneous/nz-map-definition.pdf
+
+2. OSG Technical Report 4.1
+ http://www.linz.govt.nz/docs/miscellaneous/nzmg.pdf
+
+
+IMPLEMENTATION NOTES
+
+The two references use different symbols for the calculated values. This
+implementation uses the variable names similar to the symbols in reference [1].
+
+The alogrithm uses different units for delta latitude and delta longitude.
+The delta latitude is assumed to be in units of seconds of arc x 10^-5.
+The delta longitude is the usual radians. Look out for these conversions.
+
+The algorithm is described using complex arithmetic. There were three
+options:
+ * find and use a Javascript library for complex arithmetic
+ * write my own complex library
+ * expand the complex arithmetic by hand to simple arithmetic
+
+This implementation has expanded the complex multiplication operations
+into parallel simple arithmetic operations for the real and imaginary parts.
+The imaginary part is way over to the right of the display; this probably
+violates every coding standard in the world, but, to me, it makes it much
+more obvious what is going on.
+
+The following complex operations are used:
+ - addition
+ - multiplication
+ - division
+ - complex number raised to integer power
+ - summation
+
+A summary of complex arithmetic operations:
+ (from http://en.wikipedia.org/wiki/Complex_arithmetic)
+ addition: (a + bi) + (c + di) = (a + c) + (b + d)i
+ subtraction: (a + bi) - (c + di) = (a - c) + (b - d)i
+ multiplication: (a + bi) x (c + di) = (ac - bd) + (bc + ad)i
+ division: (a + bi) / (c + di) = [(ac + bd)/(cc + dd)] + [(bc - ad)/(cc + dd)]i
+
+The algorithm needs to calculate summations of simple and complex numbers. This is
+implemented using a for-loop, pre-loading the summed value to zero.
+
+The algorithm needs to calculate theta^2, theta^3, etc while doing a summation.
+There are three possible implementations:
+ - use Math.pow in the summation loop - except for complex numbers
+ - precalculate the values before running the loop
+ - calculate theta^n = theta^(n-1) * theta during the loop
+This implementation uses the third option for both real and complex arithmetic.
+
+For example
+ psi_n = 1;
+ sum = 0;
+ for (n = 1; n <=6; n++) {
+ psi_n1 = psi_n * psi; // calculate psi^(n+1)
+ psi_n = psi_n1;
+ sum = sum + A[n] * psi_n;
+ }

+/**
+ * Namespace: Proj4js
+ *
+ * Proj4js is a JavaScript library to transform point coordinates from one
+ * coordinate system to another, including datum transformations.
+ *
+ * This library is a port of both the Proj.4 and GCTCP C libraries to JavaScript.
+ * Enabling these transformations in the browser allows geographic data stored
+ * in different projections to be combined in browser-based web mapping
+ * applications.
+ *
+ * Proj4js must have access to coordinate system initialization strings (which
+ * are the same as for PROJ.4 command line). Thes can be included in your
+ * application using a <script> tag or Proj4js can load CS initialization
+ * strings from a local directory or a web service such as spatialreference.org.
+ *
+ * Similarly, Proj4js must have access to projection transform code. These can
+ * be included individually using a <script> tag in your page, built into a
+ * custom build of Proj4js or loaded dynamically at run-time. Using the
+ * -combined and -compressed versions of Proj4js includes all projection class
+ * code by default.
+ *
+ * Note that dynamic loading of defs and code happens ascynchrously, check the
+ * Proj.readyToUse flag before using the Proj object. If the defs and code
+ * required by your application are loaded through script tags, dynamic loading
+ * is not required and the Proj object will be readyToUse on return from the
+ * constructor.
+ *
+ * All coordinates are handled as points which have a .x and a .y property
+ * which will be modified in place.
+ *
+ * Override Proj4js.reportError for output of alerts and warnings.
+ *
+ * See http://trac.osgeo.org/proj4js/wiki/UserGuide for full details.

+NAME LAMBERT CYLINDRICAL EQUAL AREA
+
+PURPOSE: Transforms input longitude and latitude to Easting and
+ Northing for the Lambert Cylindrical Equal Area projection.
+ This class of projection includes the Behrmann and

+
+This function was adapted from the Miller Cylindrical Projection in the Proj4JS
+library.
+
+Note: This implementation assumes a Spherical Earth. The (commented) code
+has been included for the ellipsoidal forward transform, but derivation of
+the ellispoidal inverse transform is beyond me. Note that most of the
+Proj4JS implementations do NOT currently support ellipsoidal figures.
+Therefore this is not seen as a problem - especially this lack of support
+is explicitly stated here.

+NAME NEW ZEALAND MAP GRID
+
+PURPOSE: Transforms input longitude and latitude to Easting and
+ Northing for the New Zealand Map Grid projection. The
+ longitude and latitude must be in radians. The Easting
+ and Northing values will be returned in meters.
+
+
+ALGORITHM REFERENCES
+
+1. Department of Land and Survey Technical Circular 1973/32
+ http://www.linz.govt.nz/docs/miscellaneous/nz-map-definition.pdf
+
+2. OSG Technical Report 4.1
+ http://www.linz.govt.nz/docs/miscellaneous/nzmg.pdf
+
+
+IMPLEMENTATION NOTES
+
+The two references use different symbols for the calculated values. This
+implementation uses the variable names similar to the symbols in reference [1].
+
+The alogrithm uses different units for delta latitude and delta longitude.
+The delta latitude is assumed to be in units of seconds of arc x 10^-5.
+The delta longitude is the usual radians. Look out for these conversions.
+
+The algorithm is described using complex arithmetic. There were three
+options:
+ * find and use a Javascript library for complex arithmetic
+ * write my own complex library
+ * expand the complex arithmetic by hand to simple arithmetic
+
+This implementation has expanded the complex multiplication operations
+into parallel simple arithmetic operations for the real and imaginary parts.
+The imaginary part is way over to the right of the display; this probably
+violates every coding standard in the world, but, to me, it makes it much
+more obvious what is going on.
+
+The following complex operations are used:
+ - addition
+ - multiplication
+ - division
+ - complex number raised to integer power
+ - summation
+
+A summary of complex arithmetic operations:
+ (from http://en.wikipedia.org/wiki/Complex_arithmetic)
+ addition: (a + bi) + (c + di) = (a + c) + (b + d)i
+ subtraction: (a + bi) - (c + di) = (a - c) + (b - d)i
+ multiplication: (a + bi) x (c + di) = (ac - bd) + (bc + ad)i
+ division: (a + bi) / (c + di) = [(ac + bd)/(cc + dd)] + [(bc - ad)/(cc + dd)]i
+
+The algorithm needs to calculate summations of simple and complex numbers. This is
+implemented using a for-loop, pre-loading the summed value to zero.
+
+The algorithm needs to calculate theta^2, theta^3, etc while doing a summation.
+There are three possible implementations:
+ - use Math.pow in the summation loop - except for complex numbers
+ - precalculate the values before running the loop
+ - calculate theta^n = theta^(n-1) * theta during the loop
+This implementation uses the third option for both real and complex arithmetic.
+
+For example
+ psi_n = 1;
+ sum = 0;
+ for (n = 1; n <=6; n++) {
+ psi_n1 = psi_n * psi; // calculate psi^(n+1)
+ psi_n = psi_n1;
+ sum = sum + A[n] * psi_n;
+ }

+# mergejs.py <output.js> <directory> [...]
+#
+# e.g.
+#
+# mergejs.py openlayers.js Geo/ CrossBrowser/
+#
+# This example will cause the script to walk the `Geo` and
