# A simple script to generate the configure script for a wxCode component
# Some features of this version:
# - automatic test for aclocal version
# - able to be called from any folder
#   (i.e. you can call it typing 'build/acregen.sh', not only './acregen.sh')


# called when an old version of aclocal is found
