The xrootd preload library allows standard POSIX I/O calls to xrootd servered files in stead of calls to the local file system.
The script xrdprel should be used to run a command using the xrootd preload library. The script sets the proper environment variables (LD_LIBRARY_PATH, LD_PRELOAD)
and then executes the provided command. The usage is:
xrdprel [-g] [-h] _command_ _args_ _command_ and _args_ are the user command and and its arguments -y: prints a help -g: use a virtual mountpoint, which means file names starting with /glast/ are assumed to be xrootd files.
