 ## Usage
-  To prepare your repository for the conversion pull all changes from
-  `http://hg.fast-downward.org`. Then run the script with the following 
-  command where MERCURIAL_REPOSITORY is the path to the 
-  repository you want to convert and CONVERTED_GIT_REPOSITORY is the location where the
-  resulting Git repository will be written to. The optional parameter can be used to 
-  redirect the output of fast-export to a file.
-
-    ./run-all-steps.sh MERCURIAL_REPOSITORY CONVERTED_GIT_REPOSITORY \
-        [--redirect-fast-export-stderr FILE]
 
-  The conversion is done in two steps that can also be run individually. In this case
-  ORDERED_REPOSITORY is an intermediate repository that ensures that the history
-  contains all commits in the same order as the Fast Downward master repository.
-  The CLEANED_MERCURIAL_REPOSITORY is a location where the intermediate cleaned
-  up Mercurial repository will be written to:
-  
-    ./run-cleanup.sh MERCURIAL_REPOSITORY ORDERED_REPOSITORY CLEANED_MERCURIAL_REPOSITORY

 ## Limitations
-  - Multiple Mercurial heads with the same branch name are not supported. If your
-    repository has those, you will see
-    `Error: repository has at least one unnamed head: hg rXXX`.
-  - If you have closed and merged a branch "subfeature" into a branch "feature"
-    and "feature" is not yet merged into "main", you will receive:
-    `error: The branch 'BRANCH' is not fully merged.`
-    Don't worry. You might want to delete "subfeature"
-    branch from the resulting Git repository by running `git branch -D subfeature`.

 ## Warnings
-  - The `run-cleanup.sh` and `run-conversion.sh` scripts generate a lot of output 
-    on stdout and stderr. If you want to analyze it, better redirect it into files.
-  - The cleanup script generates repeated warnings about missing or invalid tags.
-    These are caused by moved or broken tags and can be ignored.

 ## Troubleshooting
-  If you have problems with the `run-all-steps.sh` script, try to run the steps
-  individually and carefully inspect the output of each step.

 ## Details of the cleanup process
-  - clone the (Mercurial) Fast Downward master repository
-  - pull your repository in the master repository
-  - fix and unify author names in commit message
-  - fix typos in branch names
-  - remove large files from history that should not have been added
-  - change commit message to follow the new convention which is to start with
-    "`[BRANCH NAME] `"
-  - strip the open branches `issue323` and `ipc-2011-fixes`

 ## Details of the conversion process
-  - convert a Mercurial repository to Git with `fast-export`
-  - delete all Git branches that belong to Mercurial branches which have been
-    merged and closed
-  - remove empty commits
-  - run garbage collections
