 interactively select changes to commit
 
     If a list of files is omitted, all changes reported by "hg status" will be
     candidates for recording.
 
     See 'hg help dates' for a list of formats valid for -d/--date.
 
     You will be prompted for whether to record changes to each modified file,
     and for files with multiple changes, for each change to use. For each
     query, the following responses are possible:
 
       y - record this change
       n - skip this change
 
       s - skip remaining changes to this file
       f - record remaining changes to this file
 
       d - done, skip remaining changes and files
       a - record all changes to all remaining files
       q - quit, recording no changes
 
       ? - display help
 
 options:
 
  -A --addremove     mark new/missing files as added/removed before committing
     --close-branch  mark a branch as closed, hiding it from the branch list
  -I --include       include names matching the given patterns
  -X --exclude       exclude names matching the given patterns
  -m --message       use <text> as commit message
  -l --logfile       read commit message from <file>
