38 * shexp.h: Defines and prototypes for shell exp. match routines
39 * 
40 *
41 * This routine will match a string with a shell expression. The expressions
42 * accepted are based loosely on the expressions accepted by zsh.
43 * 
44 * o * matches anything
45 * o ? matches one character
46 * o \ will escape a special character
47 * o $ matches the end of the string
48 * o [abc] matches one occurence of a, b, or c. The only character that needs
49 *         to be escaped in this is ], all others are not special.
50 * o [a-z] matches any character between a and z
51 * o [^az] matches any character except a or z
52 * o ~ followed by another shell expression will remove any pattern
53 *     matching the shell expression from the match list
54 * o (foo|bar) will match either the substring foo, or the substring bar.
55 *             These can be shell expressions as well.
56 * 
57 * The public interface to these routines is documented below.
