+With this patch, address completion candidates are shown automatically\r
+after short typing delay in a nice popup box. This requires company-mode\r
+to be installed and it works only on Emacs >= 24. The completion is\r
+based entirely on the asynchronous address harvesting from\r
+notmuch-address.el so the GUI is theoretically not blocked for long\r
+time.\r
+\r
+The completion works similarly as the TAB-initiated completion from\r
+notmuch-address.el, i.e. quick harvest based on user input is executed\r
+first and only after full harvesting is finished, in-memory cached data\r
+is used.\r
+\r
+The notmuch-company.el is excluded from byte-compilation, because it\r
+would require every person who want to compile notmuch to have\r
+company-mode installed.\r
