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

32 | "Fetch REVISION from URL into DIRECTORY. REVISION must be a valid Bazaar | |
33 | revision identifier. Return #t on success, else throw an exception." | |
34 | ;; Do not attempt to write .bzr.log to $HOME, which doesn't exist. | |
35 | (setenv "BZR_LOG" "/dev/null") | |
36 | ;; Disable SSL certificate verification; we rely on the hash instead. | |
