+                         Version Release instructions for Linux Only
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are 3 archives that are built for a given release (starting with versions 
+after 3.6.0). In order to build a release you must have all files checked out
+of svn for that specific release (example: trunk)
+
+To set the current version for release, modify the file mk/linux/mg-version.sh
+and change the two variables:
+
+OLD_MG_VERSION=3.6.0.1
+MG_VERSION=3.6.0.2
+
+*Note: Please ensure the MG_VERSION variable matches the version set in the 
+MegaGlest binary, thius can be checked by running: ./megaglest --version
+It is possible to have the mg-version.sh script NOT match the binary in cases
+where we are releasing binary compatible updates to the archives in which case 
+we typically use a forth digit in the version # (as seen above)
+
+#1. The source archive:
+This archive contains source code for binary compilation of the application and 
+tools
+
+The naming convention for the source archive is:
+megaglest-source-<VERSION>.tar.xz
+
+To build this archive open a terminal and from the mk/linux folder run:
+./makerelease.sh
+
+This will produce megaglest-source-<VERSION>.tar.xz in the release subfolder
+
+#2. The data archive:
+This archive contains pre-compiled data content which is used by the game and 
+its tools
+
+The naming convention for the data archive is:
+megaglest-data-<VERSION>.tar.xz
+
+To build this archive open a terminal and from the mk/linux folder run:
+./makedata.sh
+
+This will produce megaglest-data-<VERSION>.tar.xz in the release subfolder
+
+
+#3. The data source archive:
+This archive contains data source (such as .blend files) for people to mod 
+original game data content
+
+The naming convention for the data source archive is:
+megaglest-data-source-<VERSION>.tar.xz
+
+To build this archive open a terminal and from the mk/linux folder run:
+./makedata-source.sh
+
+This will produce megaglest-data-source-<VERSION>.tar.xz in the release subfolder
+*NOTE: Currently this script only works for the trunk level release
+
