# [SYNOPSIS](#SYNOPSIS)

```
    scan-perl-prereqs [--by-file] [--pretty] [DIRS | FILES]
```

Directories are traversed with File::Find to collect all ".pl", ".pm", ".psgi" and ".t" files. If no directories or files are specified, the current working directory is scanned.

The default is to print a single combined list suitable for piping to "cpanm" or similar tools.

The "--by-file" switch will print results grouped by the files in which they were found.

The "--pretty" swith will print results in a more human-friendly format, with names and versions vertically aligned.
