-The config file syntax changed between versions 0.8 and 0.9. In order
-to implement all of the feature/enhancement requests in an elegant and
-self-consistent way, the configuration grammar had to be changed in a
-non-backward-compatible way. In particular, groups are now values, so
-the old syntax:
-
-group
-{
-  ...
-}
-
-must now be written as:
-
-group =
-{
-  ...
-};
-
-Note that the trailing semicolon, which was previously optional, is
-now required. Also note that a colon (':') can be used in place of the
-equals sign.

+To cross-compile for Android:
+
+1) Create a standalone toolchain using the 'make-standalone-toolchain.sh'
+script included with the Android NDK. For example:
+
+$ /pkg/android-ndk-r9d/build/tools/make-standalone-toolchain.sh \
+  --platform=android-19 \
+  --install-dir=/pkg/android-toolchain-19 \
+  --system=linux-x86_64 \
+  --arch=arm
+
+2) Add the standalone toolchain's bin directory to the front of the path:
+
+$ export PATH=/pkg/android-toolchain-19/bin:$PATH
+
+3) Configure libconfig for cross-compilation:
+
+$ ./configure --host=arm-linux-androideabi \
