+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and

+# You must make exactly 11 lines for the formatting to be correct. It's also

+; TEST.CTL - Sample Control File for D52
+;
+; Control codes allowed in the CTL file:
+;
+; A - Address Specifies that the word entry is the address of
+; something for which a label should be generated.
+;
+; B - Byte binary Eight bit binary data (db).
+;
+; C - Code Executable code that must be analyzed.
+;
+; F - SFR label Specify name for SFR.
+;
+; I - Ignore Treat as uninitialized space. Will not be dis-
+; assembled as anything unless some other valid
+; code reaches it.
+;
+; K - SFR bit Specify name for SFR bit.
+;
+; L - Label Generate a label for this address.
+;
+; M - Memory Generate a label for bit addressable memory.
+;
+; P - Patch Add inline code (macro, for example)
+;
+; R - Register Specify name for register
+; (instead of rb2r5 for example).
+;
+; S - Symbol Generate a symbol for this value.
+;
+; T - Text ASCII text (db).
+;
+; W - Word binary Sixteen bit binary data (dw).
+;
+; X - Operand name Specify special name for operand.
+;
+; # - Comment Add header comment to output file.
+;
+; ! - Inline comment Add comment to end of line.
+;
+; example labels:
+;
+l 0000 start
+l 0006 main
+l 0016 loop
+l 0024 subrtn
+l 002a vectbl
