| # This file extends the Kernel's require function and adds the | |
| # AutoReload module which allows to reload files once they have changed | |
| # on the disk. | |
| # | |
| # Basically, you just require your files as usual, and if you want to update | |
| # the files, either call AutoReload.reload(file) or AutoReload.reload_all. | |
| # | |
| # Usage: | |
| # irb -rautoload | |
