=head1 NAME
Git::SVN::Utils - utility functions used across Git::SVN
=head1 SYNOPSIS
use Git::SVN::Utils qw(functions to import);
=head1 DESCRIPTION
This module contains functions which are useful across many different
parts of Git::SVN. Mostly it's a place to put utility functions
rather than duplicate the code or have classes grabbing at other
classes.
=head1 FUNCTIONS
All functions can be imported only on request.
=head3 fatal
fatal(@message);
Display a message and exit with a fatal error code.
=cut
# Note: not certain why this is in use instead of die. Probably because
# the exit code of die is 255? Doesn't appear to be used consistently.
sub fatal (@) { print STDERR "@_\n"; exit 1 }
=head3 can_compress
my $can_compress = can_compress;
Returns true if Compress::Zlib is available, false otherwise.
=cut
my $can_compress;
sub can_compress {
return $can_compress if defined $can_compress;
return $can_compress = eval { require Compress::Zlib; };
}
