Excellent! We need all the help we can get. |

The problem with this approach is your resulting programs will be |
| 14 |
potentially rather slow. |

While gcj can indeed compile .class files (inside .jars) to binary, I've |
| 17 |
been told it can produce the most efficient of results. The source code |
| 18 |
is much richer in structure than the bytecode, and opens up for many |
| 19 |
effective optimizations which could only be reached through |
| 20 |
"idiom-recognition" (which doesn't exist for gcj yet, afaik) of the |
| 21 |
.class files. |

I suspect that you shouldn't give up on using gcj as a source compiler |
| 24 |
quite yet. This story may evolve with the whole ecj/gcjx/GPLv3 debate. |
