# CPAN::Reporter::PrereqCheck(3pm)

Modulino for prerequisite tests

## NAME

CPAN::Reporter::PrereqCheck - Modulino for prerequisite tests

## VERSION

version 1.2020

## SYNOPSIS

```
  require CPAN::Reporter::PrereqCheck;
  my $prereq_check = $INC{'CPAN/Reporter/PrereqCheck.pm'};
  my $result = qx/$perl $prereq_check < $prereq_file/;
```

## DESCRIPTION

This modulino determines whether a list of prerequisite modules are available and, if so, their version number.  It is designed to be run as a script in order to provide this information from the perspective of a subprocess, just like CPAN::Reporter's invocation of `"perl Makefile.PL"` and so on.

It reads a module name and prerequisite string pair from each line of input and prints out the module name, 0 or 1 depending on whether the prerequisite is satisfied, and the installed module version.  If the module is not available, it will print "n/a" for the version.  If the module is available but can't be loaded, it will print "broken" for the version.  Modules without a version will be treated as being of version "0".

No user serviceable parts are inside.  This modulino is packaged for internal use by CPAN::Reporter.
