Keep in mind, though, that the more stuff you put into a script the more has to be loaded once it is called. Modifying a script during runtime is a VERY BAD idea, like Corona688 already noted.
Why not create a man page? This is the intended place for such kind of information and would allow for inclusion of some text markup (using "troff"s "man" macro package) and make the information better accessible.
I hope this helps.

MAN(1) General Commands Manual MAN(1)
NAME
man - print sections of this manual
SYNOPSIS
man [ option ... ] [ chapter ] title ...
DESCRIPTION
Man locates and prints the section of this manual named title in the specified chapter. (In this context, the word `page' is often used as
a synonym for `section'.) The title is entered in lower case. The chapter number does not need a letter suffix. If no chapter is speci-
fied, the whole manual is searched for title and all occurrences of it are printed.
Options and their meanings are:
-t Phototypeset the section using troff(1).
-n Print the section on the standard output using nroff(1).
-k Display the output on a Tektronix 4014 terminal using troff(1) and tc(1).
-e Appended or prefixed to any of the above causes the manual section to be preprocessed by neqn or eqn(1); -e alone means -te.
-w Print the path names of the manual sections, but do not print the sections themselves.
(default)
Copy an already formatted manual section to the terminal, or, if none is available, act as -n. It may be necessary to use a filter
to adapt the output to the particular terminal's characteristics.
Further options, e.g. to specify the kind of terminal you have, are passed on to troff(1) or nroff. Options and chapter may be changed
before each title.
For example:
man man
would reproduce this section, as well as any other sections named man that may exist in other chapters of the manual, e.g. man(7).
FILES
/usr/man/man?/*
/usr/man/cat?/*
SEE ALSO
nroff(1), eqn(1), tc(1), man(7)
BUGS
The manual is supposed to be reproducible either on a phototypesetter or on a terminal. However, on a terminal some information is neces-
sarily lost.
