+===== Small Utility =====
+FIXME
+Create this tiny utility to view configuration files at their smallest and most readable form.
+Many support organizations insist you strip comments from config files to make them more readable.
+Create, install and make the utility executable (cut and paste the following at the command line as root):
 <file>
+cat << EOF >> /usr/local/bin/nocom
 #!/bin/sh
+# 'nocom' is a small tool to strip comments when viewing commented configuration files
+# It's not perfect and may not work for you.  Note that it strips the initial "#!/bin/sh" too.
+#
 echo ""
-cat $1 | sed -e '/^\s*;/d' | sed -e '/^\s*$/d'
+cat \$1 | sed -e '/^\s*;/d' | sed -e '/^\s*\$/d' | sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//'
-</file>
+EOF
-You should make the file executable:
-<file>
 chmod +x  /usr/local/bin/nocom
 </file>
