630 --follow-parent::
631 + This option is only relevant if we are tracking branches (using
632 + one of the repository layout options --trunk, --tags,
633 + --branches, --stdlayout). For each tracked branch, try to find
634 + out where its revision was copied from, and set
635 + a suitable parent in the first git commit for the branch.
636 This is especially helpful when we're tracking a directory
632 - that has been moved around within the repository, or if we
633 - started tracking a branch and never tracked the trunk it was
634 - descended from. This feature is enabled by default, use
637 + that has been moved around within the repository. If this
638 + feature is disabled, the branches created by 'git svn' will all
639 + be linear and not share any history, meaning that there will be
640 + no information on where branches were branched off or merged.
641 + However, following long/convoluted histories can take a long
642 + time, so disabling this feature may speed up the cloning
643 + process. This feature is enabled by default, use
644 --no-follow-parent to disable it.
