;;; 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 "brz"))
"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.
(setenv "BZR_LOG" "/dev/null")
;; Disable SSL certificate verification; we rely on the hash instead.
