Basic glob pattern syntax is the same as for the Unix shell environment.

• * matches everything up to a directory separator or end of string.
• [range] matches any character in range.
• [!range] matches any character not in range.

There are three extensions to the traditional glob syntax, taken from modern Unix shells.

• \ escapes a character that might otherwise have special meaning. For a literal "\" character, use "\\".
• ** matches everything, including a directory separator.
• (s1|s2|...) matches any of the strings s1, s2, etc.
