.SH "NAME"
Module::Math::Depends \- Convenience object for manipulating module dependencies
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a small convenience module created originally as part of
Module::Inspector but released separately, in the hope that people
might find it useful in other contexts.
.SH "METHODS"
.IX Header "METHODS"
.SS "new"
.IX Subsection "new"
.Vb 1
\&  my $deps = Module::Math::Depends\->new;
.Ve
.PP
Creates a new, empty, dependency set.
.SS "from_hash"
.IX Subsection "from_hash"
.Vb 1
\&  my $deps = Module::Math::Depends\->from_hash( \e%modules );
.Ve
.PP
Creates a new dependency set from a raw hashref of modules names
and versions.
.SS "add_module"
.IX Subsection "add_module"
.Vb 1
\&  $deps\->add_module( \*(AqMy::Module\*(Aq => \*(Aq1.23\*(Aq );
.Ve
.PP
Adds a single module dependency to the set.
.PP
Returns true, or dies on error.
.SS "merge"
.IX Subsection "merge"
.Vb 1
\&  $my_deps\->merge( $your_deps );
.Ve
.PP
The \f(CW\*(C`merge\*(C'\fR method takes another dependency set and merges it into the
current one, taking the highest version where both sets contain a module.
.PP
Returns true or dies on error.
.SS "as_string"
.IX Subsection "as_string"
.Vb 1
\&  print $depends\->as_string;
.Ve
.PP
Converts the dependency set to a simple printable string.
.SH "SUPPORT"
.IX Header "SUPPORT"
This module is stored in an Open Repository at the following address.
.PP
http://svn.ali.as/cpan/trunk/Module\-Math\-Depends <http://svn.ali.as/cpan/trunk/Module-Math-Depends>
.PP
Write access to the repository is made available automatically to any
published \s-1CPAN\s0 author, and to most other volunteers on request.
.PP
If you are able to submit your bug report in the form of new (failing)
unit tests, or can apply your fix directly instead of submitting a patch,
you are \fBstrongly\fR encouraged to do so as the author currently maintains
over 100 modules and it can take some time to deal with non-Critcal bug
reports or patches.
.PP
This will guarentee that your issue will be addressed in the next
release of the module.
.PP
If you cannot provide a direct test or fix, or don't have time to do so,
then regular bug reports are still accepted and appreciated via the \s-1CPAN\s0
bug tracker.
