# Allow bulk operations on a list of selected files.
# Requires: dmenu (or similar), trash (optional), open-file (for open only)
# Usage: sel [-m menu] [command]
# If no command is specified, shows the list of selected files
# Commands:
# add [files...]: add files to selection
# addall: add all files in the current folder to selection
# clear: clear selection
# cp: copy to current dir, possbily after editing filenames
# edit: open selection in editor
# mv: move to current dir, possbily after editing filenames
# open: open files using open-file
# rm: remove selected files and clear selection
# TODO: The usage of paste(1) is a bit of a hack, and for example it does
# not work if filenames contain tab characters. Fix this.
# Bug (probably not fixing this, use virename): moving a file to
# itself gives an error and rm is not run.
