+Release Notes
+--------------
+This version of the library has been tested under the following OS:
+- RedHat Linux 9.0
+
+You should be able to link progams with the -lopenjpeg option after the library is compiled and installed.
+You can also statically link with libopenjpeg.a.
+If you use a really old version of gcc and it chokes on the CRs in the file, you can type 'make dos2unix'
+to run all of the files through dos2unix which converts CRLF to LF. This no longer appears to be required
+for RedHat 7.3 or 9.
+
+Please let us know how this works for you under other Linux distributions or any other *nix.
+
+Installation
+------------
+Note: You will need to have root privileges in order to install the library in the /usr/lib directory.
+The installation process is as simple as this :
+1) Enter the OpenJPEG directory
+2) Build the distribution :
+make
+make install
+3) Clean all files produced during the build process
+make clean
+
--- /dev/null
+Release Notes
+--------------
+This version of the library has been tested under OSX 10.2 using gcc 3.3.
+
+While the makefiles will make a .dylib and a .a, it is recommended to simply staticly link with the .a file.
+
+Installation
+------------
+Note: You will need to have root privileges in order to install the library in the /usr/lib directory.
+The installation process is as simple as this :
+1) Enter the OpenJPEG directory
+2) Build the distribution :
+make osx
+make osxinstall
+3) Clean all files produced during the build process
+make clean
