// The specification is a space-separated list of index entries. Normally, each entry is just a single character,
|
|
// but you may also specify multiple characters. For instance, the entry "The" will link to all files and
|
|
// folders starting with "The".
|
|
//
|
|
// You may also create an entry using a group of index characters in parentheses. For instance, the entry
|
|
// "A-E(ABCDE)" will display as "A-E" and link to all files and folders starting with either
|
|
// A, B, C, D or E. This may be useful for grouping less-frequently used characters (such and X, Y and Z), or
|
|
// for grouping accented characters (such as A, \u00C0 and \u00C1)
|
|
//
|
|
// Files and folders that are not covered by an index entry will be placed under the index entry "#".
