ExtUtils::Installed provides a standard way to find out what core and
module files have been installed. It uses the information stored in
.packlist files created during installation to provide this information. In
addition it provides facilities to classify the installed files and to
extract directory information from the .packlist files.
The
new() function searches for all
the installed .packlists on the system, and stores their contents. The
.packlists can be queried with the functions described below.
This takes one mandatory parameter, the name of a module. It returns a list
of all the filenames from the package. To obtain a list of core perl files,
use the module name 'Perl'. Additional parameters are allowed. The first is
one of the strings ``prog'', ``man'' or ``all'', to select either just
program files, just manual files or all files. The remaining parameters are
a list of directories. The filenames returned will be restricted to those
under the specified directories.

files from the specified module.
This takes one mandatory parameter, the name of a module. It checks that
all the files listed in the modules .packlist actually exist, and returns a
list of any missing files. If an optional second argument which evaluates
to true is given any missing files will be removed from the .packlist
We are painfully aware that these documents may contain incorrect links and
misformatted HTML. Such bugs lie in the automatic translation process
that automatically created the hundreds and hundreds of separate documents that you find here. Please do
not report link or formatting bugs, because we cannot fix
per-document problems. The only bug reports that will help us are those
that supply working patches to the installhtml or pod2html
programs, or to the Pod::HTML module itself, for which I and the entire
Perl community will shower you with thanks and praises.
If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in
the explanations or code, please use the perlbug utility included
with the Perl distribution.
