+FFTS -- The Fastest Fourier Transform in the South
+by Anthony Blake <anthonix@me.com>
+
+To build for Android, edit and run build_android.sh
+
+To build for iOS, edit and run build_iphone.sh 
+
+To build for Linux or OS X on x86, run 
+./configure --enable-sse --enable-single --prefix=/usr/local
+make
+make install
+
+FFTS dynamically generates code at runtime. This can be disabled with 
+--disable-dynamic-code
+
+For JNI targets: --enable-jni will build the jni stuff automatically for
+the host target, and --enable-shared must also be added manually for it to
+work.
+
+If you like FFTS, please show your support by sending a postcard to:

+# SYNOPSIS
+#
+#   AX_CHECK_CLASS
+#
+# DESCRIPTION
+#
+#   AX_CHECK_CLASS tests the existence of a given Java class, either in a
+#   jar or in a '.class' file.
+#
+#   *Warning*: its success or failure can depend on a proper setting of the
+#   CLASSPATH env. variable.
+#
+#   Note: This is part of the set of autoconf M4 macros for Java programs.
+#   It is VERY IMPORTANT that you download the whole set, some macros depend
+#   on other. Unfortunately, the autoconf archive does not support the
+#   concept of set of macros, so I had to break it for submission. The
+#   general documentation, as well as the sample configure.in, is included
+#   in the AX_PROG_JAVA macro.

+#
+#   This macro assumes that unzip, zipinfo or pkzipc is avialable (and can

+#   similarly enough to the infozip versisonms. The pkzipc version is
+#   assumed to work if I undertstand the documentation on pkware's site but
+#   YMMV. I do not have access to pwkware's version to test it.

+# DESCRIPTION
+#
+#   Test if a Java class is available. Based on AX_PROG_JAVAC_WORKS. This
+#   version uses a cache variable which is both compiler, options and
+#   classpath dependent (so if you switch from javac to gcj it correctly
+#   notices and redoes the test).
+#
+#   The macro tries to compile a minimal program importing <class>. Some
+#   newer compilers moan about the failure to use this but fail or produce a
+#   class file anyway. All moaing is sunk to /dev/null since I only wanted
+#   to know if the class could be imported. This is a recommended followup
+#   to AX_CHECK_JAVA_PLUGIN with classpath appropriately adjusted.

+#   JNI include directories are usually in the java distribution This is

+#
+#   Example usage follows:

+#     AX_JNI_INCLUDE_DIR
+#
+#     for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
+#     do
+#             CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
+#     done
+#
+#   If you want to force a specific compiler:
+#
+#   - at the configure.in level, set JAVAC=yourcompiler before calling
+#   AX_JNI_INCLUDE_DIR
+#
+#   - at the configure level, setenv JAVAC
+#
+#   Note: This macro can work with the autoconf M4 macros for Java programs.

+# SYNOPSIS
+#
+#   AX_PROG_JAR
+#
+# DESCRIPTION
+#
+#   AX_PROG_JAR tests for an existing jar program. It uses the environment
+#   variable JAR then tests in sequence various common jar programs.
+#
+#   If you want to force a specific compiler:
+#
+#   - at the configure.in level, set JAR=yourcompiler before calling
+#   AX_PROG_JAR
+#
+#   - at the configure level, setenv JAR
+#
+#   You can use the JAR variable in your Makefile.in, with @JAR@.
+#
+#   Note: This macro depends on the autoconf M4 macros for Java programs. It
+#   is VERY IMPORTANT that you download that whole set, some macros depend
+#   on other. Unfortunately, the autoconf archive does not support the
+#   concept of set of macros, so I had to break it for submission.
+#
+#   The general documentation of those macros, as well as the sample
+#   configure.in, is included in the AX_PROG_JAVA macro.

+# SYNOPSIS
+#
+#   AX_PROG_JAVA
+#
+# DESCRIPTION
+#
+#   Here is a summary of the main macros:
+#
+#   AX_PROG_JAVAC: finds a Java compiler.
+#
+#   AX_PROG_JAVA: finds a Java virtual machine.
+#
+#   AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!).
+#
+#   AX_CHECK_RQRD_CLASS: finds if we have the given class and stops
+#   otherwise.
+#
+#   AX_TRY_COMPILE_JAVA: attempt to compile user given source.
+#
+#   AX_TRY_RUN_JAVA: attempt to compile and run user given source.
+#
+#   AX_JAVA_OPTIONS: adds Java configure options.
+#
+#   AX_PROG_JAVA tests an existing Java virtual machine. It uses the
+#   environment variable JAVA then tests in sequence various common Java
+#   virtual machines. For political reasons, it starts with the free ones.
+#   You *must* call [AX_PROG_JAVAC] before.
+#
+#   If you want to force a specific VM:
+#
+#   - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA
+#
+#     (but after AC_INIT)
+#
+#   - at the configure level, setenv JAVA
+#
+#   You can use the JAVA variable in your Makefile.in, with @JAVA@.
+#
+#   *Warning*: its success or failure can depend on a proper setting of the
+#   CLASSPATH env. variable.
+#
+#   TODO: allow to exclude virtual machines (rationale: most Java programs
+#   cannot run with some VM like kaffe).
+#
+#   Note: This is part of the set of autoconf M4 macros for Java programs.
+#   It is VERY IMPORTANT that you download the whole set, some macros depend
+#   on other. Unfortunately, the autoconf archive does not support the
+#   concept of set of macros, so I had to break it for submission.

+# SYNOPSIS
+#
+#   AX_PROG_JAVA_CC
+#
+# DESCRIPTION
+#
+#   Finds the appropriate java compiler on your path. By preference the java
+#   compiler is gcj, then jikes then javac.
+#
+#   The macro can take one argument specifying a space separated list of
+#   java compiler names.
+#
+#   For example:
+#
+#     AX_PROG_JAVA_CC(javac, gcj)
+#
+#   The macro also sets the compiler options variable: JAVA_CC_OPTS to
+#   something sensible:
+#
+#    - for GCJ it sets it to: @GCJ_OPTS@
+#      (if GCJ_OPTS is not yet defined then it is set to "-C")
+#
+#    - no other compiler has applicable options yet
+#
+#   Here's an example configure.in:
+#
+#     AC_INIT(Makefile.in)
+#     AX_PROG_JAVA_CC()
+#     AC_OUTPUT(Makefile)
+#     dnl End.
+#
+#   And here's the start of the Makefile.in:
+#
+#     PROJECT_ROOT      := @srcdir@
+#     # Tool definitions.
+#     JAVAC             := @JAVA_CC@
+#     JAVAC_OPTS        := @JAVA_CC_OPTS@
+#     JAR_TOOL          := @jar_tool@

+# SYNOPSIS
+#
+#   AX_PROG_JAVADOC
+#
+# DESCRIPTION
+#
+#   AX_PROG_JAVADOC tests for an existing javadoc generator. It uses the
+#   environment variable JAVADOC then tests in sequence various common
+#   javadoc generator.
+#
+#   If you want to force a specific compiler:
+#
+#   - at the configure.in level, set JAVADOC=yourgenerator before calling
+#   AX_PROG_JAVADOC
+#
+#   - at the configure level, setenv JAVADOC
+#
+#   You can use the JAVADOC variable in your Makefile.in, with @JAVADOC@.
+#
+#   Note: This macro depends on the autoconf M4 macros for Java programs. It
+#   is VERY IMPORTANT that you download that whole set, some macros depend
+#   on other. Unfortunately, the autoconf archive does not support the
+#   concept of set of macros, so I had to break it for submission.
+#
+#   The general documentation of those macros, as well as the sample
+#   configure.in, is included in the AX_PROG_JAVA macro.
