-NAME
-    git-gc-preserve - Run git gc and preserve old packs to avoid races for JGit
-SYNOPSIS
-    git gc-preserve
-DESCRIPTION
-    Runs git gc and can preserve old packs to avoid races with concurrently
-    executed commands in JGit.
-    This command uses custom git config options to configure if preserved packs
-    from the last run of git gc should be pruned and if packs should be preserved.
-    This is similar to the implementation in JGit [1] which is used by
-    JGit to avoid errors [2] in such situations.
-    The command prevents concurrent runs of the command on the same repository
-    by acquiring an exclusive file lock on the file
-      "\$repopath/gc-preserve.pid"
-    If it cannot acquire the lock it fails immediately with exit code 3.
-    Failure Exit Codes
-        1: General failure
-        2: Couldn't determine repository path. If the current working directory
-           is outside of the working tree of the git repository use git option
-           --git-dir to pass the root path of the repository.
-           E.g.
-              $ git --git-dir ~/git/foo gc-preserve
-        3: Another process already runs $0 on the same repository
-    [1] https://git.eclipse.org/r/c/jgit/jgit/+/87969
-    [2] https://git.eclipse.org/r/c/jgit/jgit/+/122288
-CONFIGURATION
-    "pack.prunepreserved": if set to "true" preserved packs from the last gc run
-      are pruned before current packs are preserved.
-    "pack.preserveoldpacks": if set to "true" current packs will be hard linked
-      to objects/pack/preserved before git gc is executed. JGit will
-      fallback to the preserved packs in this directory in case it comes
-      across missing objects which might be caused by a concurrent run of
-      git gc.
