1. find_lib(lib.s) - obsolete but maybe usefull to get the path of a lib searches a lib.so
Returns: full path (i.e. /usr/lib/libgtk-2.so) (only one!!! file is returned.....)
2. find_file (file.s, start.s, nosearch.s) - find files containing the string file.s starting in directory start.s and excluding directories containing string in nosearch. All directories from start.s on are searched recursively
Returns: a #LF$ separated list of files with full path (be carefull with "/" as starting directory

3. find_proc(proc.s) finds running processes containing the string in proc.s
Returns: a #LF$ separated list with all matching processes
(If proc.s is empty, all processes are returned)
