Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

;; Support for evaluating clojure code
|
|
|
|
;; Requirements:
|
|
|
|
;; - clojure (at least 1.2.0)
|
|
;; - clojure-mode
|
|
;; - either cider or SLIME
|
|
|
|
;; For Cider, see https://github.com/clojure-emacs/cider
|
|
|
|
;; For SLIME, the best way to install these components is by following
|
|
;; the directions as set out by Phil Hagelberg (Technomancy) on the
|
|
;; web page: http://technomancy.us/126
