    NAME

    ====

    B{C{r.WarnScriptSharedLibrary()}} - Warn about scripts which modify

    C{ld.so.conf}-related files

    SYNOPSIS

    ========

    C{r.WarnScriptSharedLibrary([I{filterexp}] I{exceptions=filterexp}])}

    DESCRIPTION

    ===========

    The C{r.WarnScriptSharedLibrary()} policy inspects capsule scripts

    for mentions of C{ld.so.conf} and raises an error if any mentions

    are found that are not explicitly allowed as exceptions.

    EXAMPLES

    ========

    C{r.WarnScriptSharedLibrary(exceptions='postin')}

    Do not warn about C{ld.so.conf} in any postin scripts.

    C{r.WarnScriptSharedLibrary(exceptions='foo-1.0-1.*/prein')}

    Do not warn about C{ld.so.conf} in any prein scripts for capsules

    with names starting with C{foo-1.0-1}.
