Usage: whenwasit [options] PATH
```

little thing meant to be called in a git-hook as to keep track of
file creation and modification dates, which are important to me.
dumps csv output on stdout, errors abort with a panic
*(this will be fixed later)*.

Use the `--format` flag *(`-f`)* to switch between outputting
`json` or `csv`. the default is `csv`.

The flag `--ignore` can be used to ignore paths relative to
the one whenwasit was given. See [.whenwasit-ignore](.whenwasit-ignore)
as an example.

For an example on how you might use whenwasit as a git hook, see
[pre-commit](pre-commit). It runs whenwasit before commit,
makes the file [times.csv](times.csv), and adds it to the commit.

**CSV Output Definition:**  
because there are varying ways to make a CSV, it's described in detail below.

- there is no header; the first row is data
- the data rows are in the format `path,btime,mtime,atime`
	- `path`: file path relative to the root that was provided on the command line
	- `btime`: time of file creation; birth time
	- `mtime`: time file was last modified
	- `atime`: time file was last accessed
- if the `path` contains a comma (`,`) or a backslash (`\`), it is escape with a backslash
- if any one of the time cannot be attained, the field is left empty.

**behavior:**  
prints a row for the current directory, a row for each file, and
then goes into each directory recursively.

this results in reading the directory twice as to not cache the
directory listings in memory.
