| 6261 FEXP can be a symbol, a number, or a list. | |

| 6270 If it is a list whose car is the symbol `not', it will return | |

| 6276 => ; Non-nil on XEmacs. | |
| 6277 | |

| 6280 | |
| 6281 (featurep '(or tty-frames (and emacs 19.30))) | |

| 6283 | |
| 6284 (featurep '(or (and xemacs 19.15) (and emacs 19.34))) | |
