# All Module::Install core packages now require synchronised versions.
# This will be used to ensure we don't accidentally load old or
# different versions of modules.
# This is not enforced yet, but will be some time in the next few
# releases once we can make sure it won't clash with custom
# Module::Install extensions.

# Whether or not inc::Module::Install is actually loaded, the
# $INC{inc/Module/Install.pm} is what will still get set as long as
# the caller loaded module this in the documented manner.
# If not set, the caller may NOT have loaded the bundled version, and thus
# they may not have a MI version that works with the Makefile.PL. This would
# result in false errors or unexpected behaviour. And we don't want that.

# If the script that is loading Module::Install is from the future,
# then make will detect this and cause it to re-run over and over
# again. This is bad. Rather than taking action to touch it (which
# is unreliable on some platforms and requires write permissions)
# for now we should catch this and refuse to run.
if ( -f $0 and (stat($0))[9] > time ) { die <<"END_DIE" }
Your installer $0 has a modification time in the future.
This is known to create infinite loops in make.
Please correct this, then run $0 again.

# Build.PL was formerly supported, but no longer is due to excessive
# difficulty in implementing every single feature twice.
if ( $0 =~ /Build.PL$/i ) { die <<"END_DIE" }
Module::Install no longer supports Build.PL.
It was impossible to maintain duel backends, and has been deprecated.
Please remove all Build.PL files and only use the Makefile.PL installer.
