        "DESCRIPTION": {
            "content": "svn-bisect  helps  to automate finding a bug or behavior change in a Subversion working copy.\nGiven an initial “good” revision, with the desired or original behavior, and  a  newer  “bad”\nrevision, with the undesired or modified behavior, svn-bisect will do a binary search through\nthe revision range to find which revision caused the change.\n\nsvn-bisect must be initialized in a working copy, with svn-bisect start.  It also needs to be\ngiven  at  least one good revision (the baseline) and one bad revision (known modified behav‐\nior) revision.\n\nSub-commands:\n\nstart  Initializes or reinitializes svn-bisect; optionally takes good and bad revision param‐\neters.\n\ngood rev\n\nbad rev\nTells  svn-bisect  that  a  revision  is good or bad, defining or narrowing the search\nspace.  If not specified, revision defaults to the current  revision  in  the  working\ncopy.   svn-bisect will then update to a revision halfway between the new good and bad\nboundaries.  If this update crosses a point where a branch was created, it switches in\nor out of the branch.\n\nreset  Resets the working copy to the revision and branch where svn-bisect start was run.  In\nthe simple case this is equivalent to rm -r .svn-bisect; svn update, but not if it has\ncrossed  branches,  and  not  if you did not start at the HEAD revision.  In any case,\nsvn-bisect never keeps track of mixed-revision working copies, so do not  use  svn-bi‐‐\nsect in a working copy that will need to be restored to mixed revisions.\n\nstatus Prints a brief status message.\n\nrun command\nRuns  the  bisection  in  a  loop.  You must have already defined initial good and bad\nboundary conditions.  Each iteration through the loop runs command as a shell  command\n(a  single argument, quoted if necessary) on the chosen revision, then marks the revi‐\nsion as good or bad, based on the exit status of command.\n",
