 Use `fatrace` to record all file access during an `sbuild` run and find those
 build dependencies which have their files never needed. You need superuser

 This needs the --pre-realbuild-commands and --post-realbuild-commands to exist
 which can be added to sbuild by applying
 `0001-add-pre-realbuild-commands-and-post-realbuild-comman.patch` to it.
 
-Any unused dependencies can then be found by investigating the file
-`unneededdepends.list`.
+The first pass will use `fatrace` to find build dependencies on packages with

+be meta packages, a second pass replaces the candidate package with a fake
+equivs package of same name and version but without dependencies and tries to
+rebuild.
 
-Batch
------
-
-The process can be automated for multiple packages by passing `dsc` files to
-`run.sh`:
-
-	$ ./run.sh ../mysources/*.dsc
-
-This script will put the successful builds in `buildsuccess.list` and the found
-unused build dependencies as `*.unusedbd` for each `dsc` file in the current
-directory. A second pass on the successfully built `dsc` files will then check
-each of the found unused build dependencies for their validity by replacing
-them by an empty equivs package with no dependencies one after another. The
-results of that run are stored in `*.unusedbd.real` files for each `dsc` file
-in the current directory.  The `run.sh` script expects to find
-`findunusedbd.sh` directly under `/home`.  Best try this out in a chroot to not
-mess with the host system.
+Both passes are done for `--arch-all` and `--no-arch-all`. Any unused
+dependencies can then be found by investigating the `*.arch-all.unusedbd.real`
+and `*.no-arch-all.unusedbd.real`. The result from the former can permanently
+be dropped from the `Build-Depends`. The result from the latter can be added to
+`Build-Depends-Indep`.
