You can use the command man tr and will find the -s switch which stands for substitute. But now you might not have to look it up anymore.

NAME
docidx_lang_syntax - docidx language syntax
DESCRIPTION
This document contains the formal specification of the syntax of the docidx markup language, version 1 in Backus-Naur-Form. This document
is intended to be a reference, complementing the docidx language command reference. A beginner should read the much more informally writ-
ten docidx language introduction first before trying to understand either this document or the command reference.
FUNDAMENTALS
In the broadest terms possible the docidx markup language is like SGML and similar languages. A document written in this language consists
primarily of markup commands, with text embedded into it at some places.
Each markup command is a just Tcl command surrounded by a matching pair of [ and ]. Which commands are available, and their arguments, i.e.
syntax is specified in the docidx language command reference.
In this document we specify first the lexeme, and then the syntax, i.e. how we can mix text and markup commands with each other.
LEXICAL DEFINITIONS
In the syntax rules listed in the next section
[1] <TEXT> stands for all text except markup commands.
[2] Any XXX stands for the markup command [xxx] including its arguments. Each markup command is a Tcl command surrounded by a matching
pair of [ and ]. Inside of these delimiters the usual rules for a Tcl command apply with regard to word quotation, nested commands,
continuation lines, etc.
[3] <WHITE> stands for all text consisting only of spaces, newlines, tabulators and the comment markup command.
SYNTAX
The rules listed here specify only the syntax of docidx documents. The lexical level of the language was covered in the previous section.
Regarding the syntax of the (E)BNF itself
[1] The construct { X } stands for zero or more occurrences of X.
[2] The construct [ X ] stands for zero or one occurrence of X.
The syntax:
index = defs
INDEX_BEGIN
contents
INDEX_END
{ <WHITE> }
defs = { INCLUDE | VSET | <WHITE> }
contents = keyword { keyword }
keyword = defs KEY ref { ref }
ref = MANPAGE | URL | defs
