.SH "NAME"
Perl::PrereqScanner::Scanner::Perl5 \- scan for core Perl 5 language indicators of required modules
.SH "VERSION"
.IX Header "VERSION"
version 1.100
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This scanner will look for the following indicators:
.IP "\(bu" 4
plain lines beginning with \f(CW\*(C`use\*(C'\fR, \f(CW\*(C`require\*(C'\fR, or \f(CW\*(C`no\*(C'\fR in your perl modules and scripts, including minimum perl version
.IP "\(bu" 4
regular inheritance declared with the \f(CW\*(C`base\*(C'\fR and \f(CW\*(C`parent\*(C'\fR pragmata
.PP
Since Perl does not allow you to supply a version requirement with a
\&\f(CW\*(C`require\*(C'\fR statement, the scanner will check the statement after the
\&\f(CW\*(C`require Module\*(C'\fR to see if it is \f(CW\*(C`Module\->VERSION( minimum_version );\*(C'\fR.
.PP
In order to provide a minimum version, that method call must meet the
following requirements:
.IP "\(bu" 4
it must be the very next statement after \f(CW\*(C`require Module\*(C'\fR.  Nothing can separate them but whitespace and comments (and one semicolon).
.IP "\(bu" 4
\&\f(CW\*(C`Module\*(C'\fR must be a bareword, and match the \f(CW\*(C`require\*(C'\fR exactly.
.IP "\(bu" 4
\&\f(CW\*(C`minimum_version\*(C'\fR must be a literal number, v\-string, or single-quoted string.  Double quotes are not allowed.
.SH "PERL VERSION"
.IX Header "PERL VERSION"
This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.
.PP
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.
