= TolPackage =

!TolPackage is a TOL '''module''' (part of TolCore) for the TOL-packages management: installation, updating and upgrading, loading, creation, etc.


== History ==

The !TolPackage module evolves with the TOL-package design and enhacements, causing different versions with their own mechanisms and functionalities.

These versions are briefly described below.

=== Version 1 ===

!TolPackage first version has been distributed from TOL version {{{2.0.1}}} (see [2224]) to TOL versión {{{3.1 p009}}} (see [4535]).

This was the development version and it shows different enhancements in its two different subversions: {{{1.0}}} and {{{1.1}}}.

=== Version 2 ===

From TOL version {{{3.1 p010}}} (see [4622]) a new version of !TolPackage: {{{2}}} is available. This version was created to solve some difficulties with previous version.

=== Version 3 ===

To solve an OIS incompatibility in early patchs of TOL version {{{3.2}}} a new version of !TolPackage: {{{3}}} was created. This third version was used simultaneously with version {{{2}}}.

See tickets: #1541, #1533.

The mentioned incompatibility was solved in [5428] and since then the !TolPackage duality (versions {{{2}}} and {{{3}}} simultaneity) is no longer necessary.

=== Version 4 ===

New TOL versions for Windows (MinGW compiled) incorporate an incompatibility with TOL packages including binary libraries (.dll files). 

This difficulty causes the development of a new version: {{{4}}}. See ticket: #1821. 

!TolPackage.4 provides the possibility of managing different TOL-package variants (compatible with different TOL platforms) for the same TOL-package version.
