Hi All, 

Here is a patch http://review.gluster.org/#/c/13061/ that creates the initial template for any new xlator that you wish to write. 

How to use: 
$ python ./generate_xlator.py <XLATOR_DIRECTORY> <XLATOR_NAME> <FOP_SUFFIX> 

Eg: python ./generate_xlator.py /home/u1/glusterfs/xlators/features compression cmpr
This command will create the following files with some initial contents like copyright, fops definition, header definition etc. : 
* /home/u1/glusterfs/xlators/features/compression/Makefile.am 
* /home/u1/glusterfs/xlators/features/compression/src/Makefile.am 
* /home/u1/glusterfs/xlators/features/compression/src/compression.c 
* /home/u1/glusterfs/xlators/features/compression/src/compression.h 
* /home/u1/glusterfs/xlators/features/compression/src/compression-mem-types.h 
* /home/u1/glusterfs/xlators/features/compression/src/compression-messages.h 

By default all the fops and other functions are generated, if you do not need to implement certain functions, delete those functions from the the file `config.py`. 
One can customize the fop definition by changing CBK_TEMPLATE/FOP_TEMPLATE in generate_xlator.py.

This is an addition to Jeff's http://review.gluster.org/#/c/9411/
Reviews are welcome.

Merry Christmas:)
