new file mode 100644@@ -0,0 +1,81 @@+This is the readme.txt for the decNumber package.  It includes
+instructions for compiling and testing the package; please read them.
+---------------------------------------------------------------------
+
+decNumber is distributed in two forms; as a complete package from
+the International Components for Unicode (ICU) site (under an as-is
+license), or as a collection of Open Source files from the GCC source
+repository (under the GPL license).
+
+If you are using the GCC files, you can obtain the documentation, the
+example files mentioned below, and this readme from the General
+Decimal Arithmetic web page -- http://speleotrove.com/decimal/ (the
+URL for the open source files is also linked from there).
+
+
+The ICU package
+---------------
+
+The ICU package includes the files:
+
+  *  readme.txt (this file)
+
+  *  ICU-license.html
+
+  *  decNumber.pdf (documentation)
+
+  *  The .c and .h file for each module in the package (see the
+     decNumber documentation), together with other included files.
+
+  *  The .c files for each of the examples (example1.c through
+     example8.c).
+
+The ICU package is made available under the terms of the ICU License
+(ICU 1.8.1 and later) included in the package as ICU-license.html.
+Your use of that package indicates your acceptance of the terms and
+conditions of that Agreement.
+
+
+To use and check decNumber
+--------------------------
+
+  Please read the appropriate license and documentation before using
+  this package.  If you are upgrading an existing use of decNumber
+  (with version <= 3.37) please read the Changes Appendix for later
+  versions -- you may need to change the DECLITEND flag.
+
+  1. Compile and link example1.c, decNumber.c, and decContext.c
+     For instance, use:
+
+       gcc -o example1 example1.c decNumber.c decContext.c
+
+     Note: If your compiler does not provide stdint.h or if your C
+     compiler does not handle line comments (// ...), then see the
+     User's Guide section in the documentation for further information
+     (including a sample minimal stdint.h).
+
+     The use of compiler optimization is strongly recommended (e.g.,
+     -O3 for GCC or /O2 for Visual Studio).
+
+  2. Run example1 with two numeric arguments, for example:
+
+       example1 1.23 1.27
+
+     this should display:
+
+       1.23 + 1.27 => 2.50
+
+  3. Similarly, try the other examples, at will.
+
+     Examples 2->4 require three files to be compiled, like Example 1.
+
+     Example 5 requires decimal64.c in addition to the core modules.
+
+     Example 6 requires decPacked.c in addition to the core modules.
+
+     Example 7 requires only example7.c decContext.c and decQuad.c
+
+     Example 8 requires example8.c, decContext.c, and decQuad.c, plus
+               decNumber.c, decimal128.c, and decimal64.c (the latter
+               for shared tables and code)
+
