You are right of course. I wouldn't have limited it if the thread-starter wouldn't have explicitly stated that the character could only be "N" or "U".
Perhaps it is a matter of programming philosophy (which is not the topic of this thread - at least not directly), i would prefer my solution over the general one followed by a line catching all the lines not matched by my solution to point them out as suspicious - lines which "shouldn't exist" at all.
The point is: if a specification says that the specific character can only be "N" or "U", then i would like to be informed if a line with neither "N" or "U" on it comes up. Maybe the specification has changed, maybe my script is faulty, maybe some pre-processing steps producing the lines are faulty - whatever. At least there is *something* that might have to be dealt with.
With all due respect

cpanplus::internals::extract
CPANPLUS::Internals::Extract(3perl) Perl Programmers Reference Guide CPANPLUS::Internals::Extract(3perl)
NAME
CPANPLUS::Internals::Extract - internals for archive extraction
SYNOPSIS
### for source files ###
$self->_gunzip( file => 'foo.gz', output => 'blah.txt' );
### for modules/packages ###
$dir = $self->_extract( module => $modobj,
extractdir => '/some/where' );
DESCRIPTION
CPANPLUS::Internals::Extract extracts compressed files for CPANPLUS. It can do this by either a pure perl solution (preferred) with the
use of "Archive::Tar" and "Compress::Zlib", or with binaries, like "gzip" and "tar".
The flow looks like this:
$cb->_extract
Delegate to Archive::Extract
METHODS
$dir = _extract( module => $modobj, [perl => '/path/to/perl', extractdir => '/path/to/extract/to', prefer_bin => BOOL, verbose => BOOL, force
=> BOOL] )
"_extract" will take a module object and extract it to "extractdir" if provided, or the default location which is obtained from your
config.
The file name is obtained by looking at "$modobj->status->fetch" and will be parsed to see if it's a tar or zip archive.
If it's a zip archive, "__unzip" will be called, otherwise "__untar" will be called. In the unlikely event the file is of neither format,
an error will be thrown.
"_extract" takes the following options:
module
A "CPANPLUS::Module" object. This is required.
extractdir
The directory to extract the archive to. By default this looks something like:
/CPANPLUS_BASE/PERL_VERSION/BUILD/MODULE_NAME
prefer_bin
A flag indicating whether you prefer a pure perl solution, ie "Archive::Tar" or "Archive::Zip" respectively, or a binary solution like
"unzip" and "tar".
perl
The path to the perl executable to use for any perl calls. Also used to determine the build version directory for extraction.
verbose
Specifies whether to be verbose or not. Defaults to your corresponding config entry.
force
Specifies whether to force the extraction or not. Defaults to your corresponding config entry.
All other options are passed on verbatim to "__unzip" or "__untar".
Returns the directory the file was extracted to on success and false on failure.
