-Introduction
-============
-* booster is a LD_PRELOADable library which boosts read/write performance by bypassing fuse for
-  read() and write() calls.
-
-Requirements
-============
-* fetch volfile from glusterfs.
-* identify whether multiple files are from the same mount point. If so, use only one context.
-
-Design
-======
-* for a getxattr, along with other attributes, fuse returns following attributes.
-  * contents of client volume-file.
-  * mount point.
-
-* LD_PRELOADed booster.so maintains an hash table storing mount-points and libglusterfsclient handles
-  so that handles are reused for files from same mount point.
-
-* it also maintains a fdtable. fdtable maps the fd (integer) returned to application to fd (pointer to fd struct)
-  used by libglusterfsclient. application is returned the same fd as the one returned from libc apis.
-
-* During fork, these tables are overwritten to enable creation of fresh glusterfs context in child.
-
-Working
-=======
-* application willing to use booster LD_PRELOADs booster.so which is a wrapper library implementing
-  open, read and write.
-
-* application should specify the path to logfile through the environment variable GLFS_BOOSTER_LOGFILE. If
-  not specified, logging is done to /dev/stderr.
-
-* open call does,
-  * real_open on the file.
-  * fgetxattr(fd).
-  * store the volume-file content got in the dictionary to a temporary file.
-  * look in the hashtable for the mount-point, if already present get the libglusterfsclient handle from the
-    hashtable. Otherwise get a new handle from libglusterfsclient (be careful about mount point not present in
-    the hashtable and multiple glusterfs_inits running simultaneously for the same mount-point there by using
-    multiple handles for the same mount point).
-  * real_close (fd).
-  * delete temporary volume-volfile.
-  * glusterfs_open (handle, path, mode).
-  * store the fd returned by glusterfs_open in the fdtable at the same index as the fd returned by real_open.
-  * return the index as fd.
-
-* read/write calls do,
-  * get the libglusterfsclient fd from fdtable.
-  * if found use glusterfs_read/glusterfs_write, else use real_read/real_write.
-
-* close call does,
-  * remove the fd from the fdtable.
-
-* other calls use real_calls.
