-What is mod_glusterfs?
-======================
-* mod_glusterfs is a module for apache written for efficient serving of files from glusterfs. 
-  mod_glusterfs interfaces with glusterfs using apis provided by libglusterfsclient.
-
-* this README speaks about installation of apache-1.3.x, where x is any minor version.
-
-Prerequisites for mod_glusterfs
-===============================
-Though mod_glusterfs has been written as a module, with an intent of making no changes to the way apache has 
-been built, currently following points have to be taken care of:
-
-* module "so" has to be enabled, for apache to support modules.
-* since glusterfs is compiled with _FILE_OFFSET_BITS=64 and __USE_FILE_OFFSET64 flags, mod_glusterfs and apache 
-  in turn have to be compiled with the above two flags.
- 
- $ tar xzvf apache-1.3.9.tar.gz
- $ cd apache-1.3.9/
- $ # add -D_FILE_OFFSET_BITS=64 -D__USE_FILE_OFFSET64 to EXTRA_CFLAGS in src/Configuration.
- $ ./configure --prefix=/usr --enable-module=so 
- $ cd src
- $ ./Configure 
- $ cd ../
- $ make install  
- $ httpd -l | grep -i mod_so 
-   mod_so.c
-
-* if multiple apache installations are present, make sure to pass --with-apxs=/path/to/apxs/of/proper/version to configure script while building glusterfs.
-
-Build/Install mod_glusterfs
-===========================
-* mod_glusterfs is provided with glusterfs--mainline--3.0 and all releases from the same branch.
-
-* building glusterfs also builds mod_glusterfs. But 'make install' of glusterfs installs mod_glusterfs.so to 
-  glusterfs install directory instead of the apache modules directory.
-
-* 'make install' of glusterfs will print a message similar to the one given below, which is self explanatory. 
-  Make sure to use apxs of proper apache version in case of multiple apache installations. This will copy 
-  mod_glusterfs.so to modules directory of proper apache version and modify the appropriate httpd.conf to enable
-  mod_glusterfs. 
-
-**********************************************************************************************
-* TO INSTALL MODGLUSTERFS, PLEASE USE,                                            
-* apxs -n mod_glusterfs -ia /usr/lib/glusterfs/1.4.0pre2/apache-1.3/mod_glusterfs.so               
-**********************************************************************************************
-
-Configuration
-=============
-* Following configuration has to be added to httpd.conf.
-
- <Location "/glusterfs">
- 	   GlusterfsLogfile "/var/log/glusterfs/glusterfs.log"
-	   GlusterfsLoglevel "warning"
- 	   GlusterfsVolumeSpecfile "/etc/glusterfs/glusterfs-client.spec"
-	   GlusterfsCacheTimeout "600"
-	   GlusterfsXattrFileSize "65536"
- 	   SetHandler "glusterfs-handler"
- </Location>
-
-* GlusterfsVolumeSpecfile (COMPULSORY)
-  Path to the the glusterfs volume specification file.
-
-* GlusterfsLogfile (COMPULSORY)
-  Path to the glusterfs logfile.
-
-* GlusterfsLoglevel (OPTIONAL, default = warning)
-  Severity of messages that are to be logged. Allowed values are critical, error, warning, debug, none 
-  in the decreasing order of severity.
-
-* GlusterfsCacheTimeOut (OPTIONAL, default = 0)
-  Timeout values for glusterfs stat and lookup cache.
-
-* GlusterfsXattrFileSize (OPTIONAL, default = 0)
-  Files with sizes upto and including this value are fetched through the extended attribute interface of 
-  glusterfs rather than the usual open-read-close set of operations. For files of small sizes, it is recommended 
-  to use extended attribute interface.
-
-* With the above configuration all the requests to httpd of the form www.example.org/glusterfs/path/to/file are 
-  served from glusterfs.
-
-Miscellaneous points
-====================
-* httpd by default runs with username "nobody" and group "nogroup". Permissions of logfile and specfile have to 
-  be set suitably.
-
-* Since mod_glusterfs runs with permissions of nobody.nogroup, glusterfs has to use only login based 
-  authentication. See docs/authentication.txt for more details. 
-
-* To copy the data served by httpd into glusterfs mountpoint, glusterfs can be started with the 
-  volume-specification file provided to mod_glusterfs. Any tool like cp can then be used.
-
-* To run in gdb, apache has to be compiled with -lpthread, since libglusterfsclient is multithreaded. 
-  If not on Linux gdb runs into errors like: 
-  "Error while reading shared library symbols:
-   Cannot find new threads: generic error"
-
-* when used with ib-verbs transport, ib_verbs initialization fails.
-  reason for this is that apache runs as non-privileged user and the amount of memory that can be 
-  locked by default is not sufficient for ib-verbs. to fix this, as root run,
-  
-  # ulimit -l unlimited
-
-  and then start apache.
- 
-TODO
-====
-* directory listing for the directories accessed through mod_glusterfs.
