Having Guile running on an embedded device is very powerful. You can add scripting capabilities to a C program and avoid some of the cross compilation -> deploy cycles by simply editing the script to change some functionality. As an example I have taken the code from the excellent introductory article Scripting with Guile. I packaged the code so that if you install the tarball or the ipk it will install both the binary and script to a suitable place.

Tarball: http://zedstar.org/tarballs/square-0.1.tar.gz

ipk: http://zedstar.org/ipk/square_0.1-r0_armv4t.ipk

After installing Guile do:

root@om-gta02 ~/ipks $ opkg install square_0.1-r0_armv4t.ipk
Installing square (0.1-r0) to root...
Configuring square
root@om-gta02 ~/ipks $ square
result of square is 49
result of square2 is 81
