+//bme2ac by ryuuou
+//takes a bunch of bms/bme files and produces .2dx and .1 files (hopefully) usable with beatmania iidx ac
+//!!!WARNING!!! THIS WILL PROBABLY FAIL HORRIBLY ON 64BIT PLATFORMS!!! Then again it might just work
+
+//still unsupported:
+//	- songs with missing wav files?
+
+//Changelog:
+// v0.6
+//	- greater accuracy in case of many bpm changes
+//	- proper longnote handling support
+// v0.5
+//	- partial support for freezenotes
+// v0.4
+//	- speedups
+//	- implemented #STOP events (_NOT_ #STP events!)
+//	- fixed a potential problem with fractional bpm
+//	- fixed a bug with file names that have '#' in them
+//	- the measure line of the last measure wasn't written out correctly
+//	- nixed decrypted.2dx; encrypted.2dx -> output.2dx
+//	- songs now end 3 seconds after the end of the last measure
+//	- added several tools:
+//	  create2dx_new, crack2dx_new, timebase_single, encrypt2dx, merge1, parse1; with sources
+// v0.3
+//	- killed debug output
+//	- standard events are now written after bpm corrections to avoid screwing with the end-song event
+//	- keysound preload events are now dynamic and always placed between keys; this should fix wrong keysounds on fast repeats once and for all
+// v0.2
+//	- implemented bpm changes
+//	- implemented changing measure sizes, this should fix a lot of offsync songs
+// v0.1
+//	- initial release
