SVN - a real Tree - An Anology

Working with SVN is somewhat like growing a tree:

• a tree has a trunk and some branches
• branches grow from the trunk, and thinner branches grow from thicker branches
• a tree can grow with a trunk and no branch (but not for long)
• a tree with branches but no trunk looks more like a bundle of twigs fallen on the floor
• if the trunk is sick, so are the branches and eventually, the whole tree can die
• if a branch is sick, you can cut it, and another one may grow
• if a branch grows too much, it may become too heavy for the trunk, and the tree will fall down
• when you feel your tree, your trunk, or a branch is nice looking, you can take a picture of it to remember how nice it was that day
