@diff.files


----------------------------------------------------------------------
@diff.files - show file differences (between "these" files and "those" files)

   Given:
      - a list of files
      - a directory name

   Show files that differ (and/or their differences) between each file
   in the given list and its corresponding file in the other directory.

   This is similar to @diff.tree, except that one main input is a list
   of files.

----------------------------------------------------------------------
usage: @diff.files [options] file1 file2 ... old_dir

----------------------------------------------------------------------
options:
   -diff_opts 'OPTS'  : add options to diff command
                        e.g. -diff_opts -w
   -diff_prog DPROG   : display diffs using DPROG (probably graphical)
                        e.g. -diff_opts meld
                        e.g. -diff_opts xxdiff    [same as -xxdiff]
                        Consider also: kdiff3, tkdiff.
   -ignore_missing    : continue even if files are missing
                        alt: -im
   -longlist          : instead of listing file, run 'ls -l' on both
                        alt: -ll
   -save              : create pdfs of diffs
   -show              : show diffs using 'diff'
   -xxdiff            : show diffs using 'xxdiff'
   -X                 : implies -xxdiff and -ignore_missing'

----------------------------------------------------------------------
examples:

   @diff.files file1             some/other/directory
