+# Execute either the real dasm, or dasm2atasm + atasm.
+# If we have dasm on the PATH, use it, otherwise fake it.
+# dasm2atasm is NOT perfect! It does however work OK for
+# fenders.dasm, fendersdbl.dasm, and loadscreen.dasm.
+
+# The .syms file format is totally different for dasm and atasm, but
+# fenders_offsets.pl can handle either one (adapt for your purposes).
+
+# If you have dasm, but want to force atasm, pass any non-empty string
+# as the second argument to this script.
+
+# Could also use "dasm2atasm -c" and ca65/ld65 to assemble, but I can't
+# seem to get ca65 or ld65 to emit a symbol file or listing (the -l
+# option doesn't work; the -m option doesn't do what I expect), so
+# I don't know any way to extract the OFFSET_* labels from ca65's output.
