This package is the shared library for perl.
Module::CPANfile is a tool to handle cpanfile format to load application specific dependencies, not just for CPAN distributions.
Print a usage message from embedded pod documentation
Pod2usage will print a usage message for the invoking script (using its embedded pod documentation) and then exit the script with the desired exit status. The usage message printed may have any one of three levels of "verboseness": If the verbose level is 0, then only a synopsis is printed. If the verbose level is 1, then the synopsis is printed along with a description (if present) of the command line options and arguments. If the verbose level is 2, then the entire manual page is printed.
The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
A set of version requirements for a CPAN dist
A CPAN::Meta::Requirements object models a set of version constraints like those specified in the META.yml or META.json files in CPAN distributions, and as defined by CPAN::Meta::Spec; It can be built up by adding more and more constraints, and it will reduce them to the simplest representation. Logically impossible constraints will be identified immediately by thrown exceptions.
Extended processing of command line options
Module Getopt::Long implements an extended getopt function called GetOptions(). This function implements the POSIX standard for command line options, with GNU extensions, while still capable of handling the traditional one-letter options.
The distribution metadata for a CPAN dist
Software distributions released to the CPAN include a META.json or, for older distributions, META.yml, which describes the distribution, its contents, and the requirements for building and installing the distribution. The data structure stored in the META.json file is described in CPAN::Meta::Spec. CPAN::Meta provides a simple class to represent this distribution metadata (or distmeta), along with some helpful methods for interrogating that data.
Stringified perl data structures, suitable for both printing and eval
Given a list of scalars or reference variables, writes out their contents in perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. Handles self-referential structures correctly. The return value can be evaled to get back an identical copy of the original reference structure. (Please do consider the security implications of eval'ing code from untrusted sources!)
