+xa (Andre Fachat's open-source 6502 cross assembler)
+
+xa is a high-speed, two-pass, portable cross-assembler. It understands
+mnemonics and generates code for NMOS 6502s (such as 6502A, 6504, 6507,
+6510, 7501, 8500, 8501, 8502...), CMOS 6502s (65C02 and Rockwell R65C02)
+and the 65816.
+
+This build includes xa's companion piece, the disassembler dxa. dxa is
+considered alpha-quality software, but is included because it's still
+very useful. It produces output that can be reassembled with xa, but
+doesn't support the 65816 CPU.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
