best way for removing comment from shell scripts -- bash

Again a comment removal requirement from me, refer my previous problem & solution for removing comment from ruby scripts: https://www.unix.com/shell-programmin...y-program.html

This time, it is for stripping of comments from Shell Script. I search for the options in bash man page, also tried searching tools. Nothing worked out.

So somebody has personal experience/knowledge in removing comments from shell program can help me ? What is the tool i should use ?

Note: Kindly dont say "grep -v '#'" as i am looking for a more promising solution, and it should remove all kind of comments from a shell script and should not remove the code part wrongly.

MDOM::Token::Comment(3pm)				User Contributed Perl Documentation				 MDOM::Token::Comment(3pm)

NAME
MDOM::Token::Comment - A comment in Makefile source code INHERITANCE
MDOM::Token::Comment isa MDOM::Token isa MDOM::Element SYNOPSIS
# This is a MDOM::Token::Comment foo: bar # So is this one echo 'hello' DESCRIPTION
In MDOM, comments are represented by "MDOM::Token::Comment" objects. These come in two flavours, line comment and inline comments. A "line comment" is a comment that stands on its own line. These comments hold their own newline and whitespace (both leading and trailing) as part of the one "MDOM::Token::Comment" object. An inline comment is a comment that appears after some code, and continues to the end of the line. This does not include whitespace, and the terminating newlines is considered a separate MDOM::Token::Whitespace token. This is largely a convenience, simplifying a lot of normal code relating to the common things people do with comments. Most commonly, it means when you "prune" or "delete" a comment, a line comment disappears taking the entire line with it, and an inline comment is removed from the inside of the line, allowing the newline to drop back onto the end of the code, as you would expect. It also means you can move comments around in blocks much more easily. For now, this is a suitably handy way to do things. However, I do reserve the right to change my mind on this one if it gets dangerously anachronistic somewhere down the line. METHODS
Only very limited methods are available, beyond those provided by our parent MDOM::Token and MDOM::Element classes. line The "line" accessor returns true if the "MDOM::Token::Comment" is a line comment, or false if it is an inline comment. SUPPORT
