[NOTE]
====
In many scripting languages, you must use double backslashes (`\\`) when defining regular expression patterns inside string literals.
This is because a single backslash (`\`) is treated as an escape character.
====

For regular expression patterns containing commas, which is also the delimiter between files in a group, the pattern can be quoted to preserve the pattern.
