The t1lib pache isn't accepted into rtems-tools.

Since the md5 might changed (due to spaces, line breaks etc... That happened to microwindows patch accepted into rtems-tool ),  so I would like to see the t1lib pach commited first and I send the patch for rsb later to fix the patch url and also add the graphics-all.bset. I've already prepared these patches.

Here is the patch for t1lib to commit into rtems-tool:
