60 matches ACL format against each line in a file.
61 Lines starting with # are treated like comments and ignored.
63 .Nm krb5_acl_match_string
64 matches ACL format against a string.
66 The ACL format has three format specifiers: s, f, and r.
67 Each specifier will retrieve one argument from the variable arguments
68 for either matching or storing data.
69 The input string is split up using " " and "\et" as a delimiter; multiple
70 " " and "\et" in a row are considered to be the same.
