# Net::DNS::SEC::Tools::BootStrap(3pm)

Optional loading of Perl modules

## NAME

Net::DNS::SEC::Tools::BootStrap - Optional loading of Perl modules

## SYNOPSIS

```
  use Net::DNS::SEC::Tools::BootStrap;
  dnssec_tools_load_mods(
     PerlModule => 'Additional help/error text'
  );
```

## DESCRIPTION

The DNSSEC-Tools package requires a number of Perl modules that are only needed by some of the tools.  This module helps determine at run-time, rather than at installation time, if the right tools are available on the system. If any module fails to load, ***dnssec\_tools\_load\_mods()*** will display an error message and calls ***exit()***.  The error message describes how to install a module via CPAN.

The arguments to ***dnssec\_tools\_load\_mods()*** are given in pairs.  Each pair is a module to try to load (and import) and a supplemental error message.  If the module fails to load, the supplemental error message will be displayed along with the installation-via-CPAN message.  If the error message consists of the string "noerror", then no error message will be displayed before the function exits.

## CAVEATS

The module will try to import any exported subroutines from the module into the *main* namespace.  This means that the *BootStrap.pm* module is likely to not be useful for importing symbols into other modules. Work-arounds for this are:

- \- import the symbols by hand

  ```
    dnssec_tools_load_mods(
       PerlModule => 'Additional help/error text'
    );
    import PerlModule qw(func1 func2);
    func1(arg1, arg2);
  ```

- \- call the fully qualified function name

  ```
    dnssec_tools_load_mods(
       PerlModule => 'Additional help/error text'
    );
    PerlModule::func1(arg1, arg2);
  ```
