It does not mean licensing fees. + + "Standard Version" refers to the Package if it has not been + modified, or has been modified only in ways explicitly requested + by the Copyright Holder. + + "Modified Version" means the Package, if it has been changed, and + such changes were not explicitly requested by the Copyright + Holder. + + "Original License" means this Artistic License as Distributed with + the Standard Version of the Package, in its current version or as + it may be modified by The Perl Foundation in the future. + + "Source" form means the source code, documentation source, and + configuration files for the Package. + + "Compiled" form means the compiled bytecode, object code, binary, + or any other form resulting from mechanical transformation or + translation of the Source form. + + +Permission for Use and Modification Without Distribution + +(1) You are permitted to use the Standard Version and create and use +Modified Versions for any purpose without restriction, provided that +you do not Distribute the Modified Version. + + +Permissions for Redistribution of the Standard Version + +(2) You may Distribute verbatim copies of the Source form of the +Standard Version of this Package in any medium without restriction, +either gratis or for a Distributor Fee, provided that you duplicate +all of the original copyright notices and associated disclaimers. At +your discretion, such verbatim copies may or may not include a +Compiled form of the Package. + +(3) You may apply any bug fixes, portability changes, and other +modifications made available from the Copyright Holder. The resulting +Package will still be considered the Standard Version, and as such +will be subject to the Original License. + + +Distribution of Modified Versions of the Package as Source + +(4) You may Distribute your Modified Version as Source (either gratis +or for a Distributor Fee, and with or without a Compiled form of the +Modified Version) provided that you clearly document how it differs +from the Standard Version, including, but not limited to, documenting +any non-standard features, executables, or modules, and provided that +you do at least ONE of the following: + + (a) make the Modified Version available to the Copyright Holder + of the Standard Version, under the Original License, so that the + Copyright Holder may include your modifications in the Standard + Version. + + (b) ensure that installation of your Modified Version does not + prevent the user installing or running the Standard Version.

Such instructions must be +valid at the time of your distribution. If these instructions, at any +time while you are carrying out such distribution, become invalid, you +must provide new instructions on demand or cease further distribution. +If you provide valid instructions or cease distribution within thirty +days after you become aware that the instructions are invalid, then +you do not forfeit any of your rights under this license. + +(6) You may Distribute a Modified Version in Compiled form without +the Source, provided that you comply with Section 4 with respect to +the Source of the Modified Version. + + +Aggregating or Linking the Package + +(7) You may aggregate the Package (either the Standard Version or +Modified Version) with other packages and Distribute the resulting +aggregation provided that you do not charge a licensing fee for the +Package.
