These scripts probably don't offer anything useful now that
lei has fleshed out read-only MH support and v2 outputs.

 =begin usage
+Incremental (or one-shot) importer of a slrnpull news spool.
+
+Since the news spool can appear as an MH folder, you may also use
+lei from public-inbox 2.0+ to convert it:
+
+        lei convert mh:$SLRNPULL_ROOT/news/foo/bar -o v2:/path/to/inbox/
+        # (and `lei daemon-kill' if you don't want the daemon to linger)
+
+But if you want to use this script:
+
         export ORIGINAL_RECIPIENT=address@example.com
-        public-inbox-init $INBOX $GIT_DIR $HTTP_URL $ORIGINAL_RECIPIENT
-        ./import_slrnspool SLRNPULL_ROOT/news/foo/bar
+        public-inbox-init -V2 $INBOX $INBOX_DIR $HTTP_URL $ORIGINAL_RECIPIENT
+        ./import_slrnspool $SLRNPULL_ROOT/news/foo/bar
