Files must end with a newline, in order to let tools like <e>diff</e> |
| 53 |
operate properly. To avoid accidental deletions, setting <e>(setq require-final-newline 'ask)</e> in your startup file will |
| 54 |
automatically check for the existence of it and ask you to add one. |

Other useful settings can be disabled backup files (by <e>(setq make-backup-files nil)</e>and <e>(setq vc-cvs-stay-local nil)</e>), |
| 58 |
so you don't clutter CVS directories and confuse repoman with it (by adding unnecessary entries into |
| 59 |
a Manifest file e.g.). Emacs can even contact the outside world by using the X servers clipboard abilities |
| 60 |
when yanking, which is activated by <e>(setq x-select-enable-clipboard t)</e>. |

For easy editing of ebuilds an Emacs mode has been created, which is |
| 68 |
found in the package <e>app-emacs/gentoo-syntax</e>. |
| 69 |
It supports ebuilds, eclasses and eselect files, highlights keywords |
| 70 |
and also provides a hook for your own customisation. |
