Keeping your Home file permissions correct

I have been a UNIX user for a long time, and in that time I have been looking for a program to set/reset all the file permissions of a complex directory hierarchy (my home) according to a configuration file of rules.

That is not the simple find-xargs-chmod rule but a program (shell/perl/c) that reads a configuration file that defines the file permissions over my whole home, and keeps them in order.

For example the top level directory of my home is accessable and readable.
This allows other users to grab and used scripts i have written (and they do), the web server to access my public_html directory. But it also means most of my other files must be kept 'closed' to others. Especially 'dot' files.

More importantly it only changes a file permissions if those permissions are wrong, so that the file does not get incrementally backed up all the time.

I have a 'kludge' script solution I have used for years, and it works well, but the exceptions to the script is a pain, and I am sure others have also had this problem. As such I want to see what is out there!

Googling only ever seems to find 'novice' reset individual file, or whole directory type solutions. Never 'set by config' solutions.

Does anyone out there know such solutions?

NAME
dh_fixperms - fix permissions of files in package build directories SYNOPSIS
dh_fixperms [debhelperoptions] [-Xitem] DESCRIPTION
dh_fixperms is a debhelper program that is responsible for setting the permissions of files and directories in package build directories to a sane state -- a state that complies with Debian policy. dh_fixperms makes all files in usr/share/doc in the package build directory (excluding files in the examples/ directory) be mode 644. It also changes the permissions of all man pages to mode 644. It removes group and other write permission from all files. It removes execute permissions from any libraries, headers, Perl modules, or desktop files that have it set. It makes all files in the standard bin and sbin directories, usr/games/ and etc/init.d executable (since v4). Finally, it removes the setuid and setgid bits from all files in the package. When the Rules-Requires-Root field has the (effective) value of binary-targets, dh_fixperms will also reset the ownership of all paths to "root:root". OPTIONS
-Xitem, --exclude item Exclude files that contain item anywhere in their filename from having their permissions changed. You may use this option multiple times to build up a list of things to exclude. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
