=head1 NAME
B<LibOMP.pm> --
=head1 SYNOPSIS
use FindBin;
use lib "$FindBin::Bin/lib";
use LibOMP;
$ENV{ LIBOMP_WORK }
$ENV{ LIBOMP_TMP }
$ENV{ LIBOMP_EXPORTS }
=head1 DESCRIPTION
The module checks C<LIBOMP_WORK>, C<LIBOMP_EXPORTS>, and C<LIBOMP_TMP> environments variables.
If a variable set, the module makes sure it is absolute. If a variable does not exist, the module
sets it to default value.
Default value for C<LIBOMP_EXPORTS> is C<$LIBOMP_WORK/exports>, for C<LIBOMP_TMP> --
C<$LIBOMP_WORK/tmp>.
Value for C<LIBOMP_WORK> is guessed. The module assumes the script (which uses the module) is
located in C<tools/> directory of libomp directory tree, and uses path of the script to calculate
C<LIBOMP_WORK>,
