;;; Commentary:

|
|
;;; This is the build-side support code of (guix bzr-download). It allows a
|
|
;;; Bazaar repository to be branched at a specific revision.

|

;;; Code:
|
|
|
|
(define* (bzr-fetch url revision directory

#:key (bzr-command "bzr"))
|
|
"Fetch REVISION from URL into DIRECTORY. REVISION must be a valid Bazaar
|
|
revision identifier. Return #t on success, else throw an exception."
|
|
;; Do not attempt to write .bzr.log to $HOME, which doesn't exist.

;; Disable SSL certificate verification; we rely on the hash instead.
