| 1 | Depends-On-Patch: g2r-basis-filename.diff |
| 2 | |
| 3 | This patch allows multiple --compare-dest or --link-dest options to be |
| 4 | used, making the transfer of some files more optimal. Note that the |
| 5 | algorithm does NOT search for the best match -- it stops at the first |
| 6 | match and uses that as the basis file for the transfer, so be sure to |
| 7 | order your arguments appropriately (the args are searched in the order |
| 8 | they are suppled). |
| 9 | |
| 10 | Before compiling, be sure to run "make proto". |
