228 USAGE:
229 bkots [ options ] [PATH...]
230
231 POSITIONAL ARGUMENTS:
232 PATH Path(s) of file(s) or directory(ies)
233
234 OPTIONS:
235 --dry-run
236 Do everything except run 'ots' commands.
237 -h, --help
238 Display help information.
239 --include-dotfiles
240 Include files and directories starting with '.' (not
241 included by default).
242 -r, --recursive
243 Consider files in dirs recursively.
244 --version
245 Display script version.
246 -v, --verbose
247 Display debugging info.
248 --
249 Mark end of options. Interpret remaining arguments as
250 positional arguments.
251
252 DESCRIPTION:
253 Scans files by file paths or directory paths provided by
254 positional arguments to see if Open Timestamps '.ots' file
255 exists. If so, attempt to upgrade and verify the '.ots'
256 file. If no '.ots' file exists, attempt to create one.
257
258 Files with a dotfile parent directory located anywhere in the
259 file path are ignored by default. (e.g. 'HEAD' in
260 '/home/user/diary/.git/logs/HEAD' because of '.git'). Dotfiles
261 themselves are also ignored by default
262 (e.g. '/home/user/.gitconfig').
263
264 Files modified less than 1 minute ago are ignored.
265
266 EXAMPLES:
267 bkots -v foo.txt
268 bkots foo.txt bar.pdf /home/username/Pictures/
