What is dnl

Hi,
 
In 'selinux-usr\policy\tunable.te', there is something like:
 
# uncomment to allow mozilla to read files in the user home directory
dnl define(`readhome')
... ...
 
Then, what is the meaning of 'dnl'? 
 
Thank you,
 Park Lee

Sir,
 
Thank you very much!
 
Your say:
>dnl is a M4 comment.

Then, as my previous letter to selinux@tycho.nsa.gov,
Would you please tell me: How to read and understand M4 macro? Is it specific to SELinux? 
 
Thanks again.
 
Yours,
Park Lee

Did you even try and find out for yourself? The first link on google for
'm4' is http://www.gnu.org/software/m4/, complete with online manual.

no, m4 is definitely not specific to se/linux.

it's typically used by autoconf and friends, and consequently
there are literally thousands of example programs out there
that use m4.

The best thing to do is to install the M4 info files (should be part of the M4 
installation) and the "pinfo" viewer for info files.  Then run "pinfo m4".
