# JsUnHaXe 0.1.2 // Mindless Labs
#
#
# Changes:
#
# v0.1.2 - fixed output file (write to outdir/basename instead of full path)
#        - fixed state machine (wrote more than needed, resulting in invalid output)
#
# v0.1.1 - output directory can be the directory 
#          containing the js files to process
#
