This is a smplest frontend to standart GNU configure script
Usage: $slf PROGRAM VERSION [new] [noinst] [srclnk] [<configure-parameters>]
Where:
* PROGRAM is a program name and at the same time - name
of subdirectory in $BASE_APPS_PREFIX (so root directory of a newely
installed software will be $BASE_APPS_PREFIX/PROGRAM)
* VERSION is a version of program that will be installed
Keyword 'new' is used to tell this script that it is
necessary to recreate symlink 'current' to point it to
this VERSION of PROGRAM
