Hi.
1) Are these lists really external files on disk or internal perl memory structures -- arrays, hashes, strings, etc.? If files, then why does the solution need to be in perl?
2) What have you tried so far? ... cheers, drl

cpanplus::internals::extract5.16
CPANPLUS::Internals::Extract(3pm) Perl Programmers Reference Guide CPANPLUS::Internals::Extract(3pm)
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.
