* Make its dependency on AC_PROG_SED and AC_PROG_GREP explicit (AC_REQUIRE)
* Depend on AX_WITH_PROG for finding out about SWIG's location
* Use AX_COMPARE_VERSION (instead of lost of customly crafted code) to compare SWIG's version to that required
* Instead of emitting a warning error out when SWIG can't be found or it doesn't satisfy the required version
* Use a ''correct'' commandline (parameters to SWIG and correct regex + substitution) to find out SWIG's version

* Partially generated by SWIG
* Partially handcrafted
* Already supports registering Lua functions as event handlers of `widget` derivatives
* Slight change in betawidget headers because the struct typedef's somehow confused the compiler
* Use libtool for linking with Lua
