8 Test::Valgrind::Command::Perl - A Test::Valgrind command that invokes perl.
16 our $VERSION = '1.15';
20 This command is the base for all C<perl>-based commands.
21 It handles the suppression generation and sets the main command-line flags.
27 use Test::Valgrind::Suppressions;
29 use base qw<Test::Valgrind::Command Test::Valgrind::Carp>;

44 The package constructor, which takes several options :
50 The C<perl> option specifies which C<perl> executable will run the arugment list given in C<args>.
56 C<inc> is a reference to an array of paths that will be passed as C<-I> to the invoked command.
62 C<$taint_mode> is a boolean that specifies if the script should be run under taint mode.
68 Other arguments are passed straight to C<< Test::Valgrind::Command->new >>.
