102. What That Means For You

103. What That Means For You
• Applications are built from lots of components.

104. What That Means For You
• Applications are built from lots of components.
• Your source code is just the glue between them.

105. What That Means For You
• Applications are built from lots of components.
• Your source code is just the glue between them.
• We have great tools for managing source code.

106. What That Means For You
• Applications are built from lots of components.
• Your source code is just the glue between them.
• We have great tools for managing source code.
• But components are the real bulk of apps.

107. What That Means For You
• Applications are built from lots of components.
• Your source code is just the glue between them.
• We have great tools for managing source code.
• But components are the real bulk of apps.
• So you need to manage components too.

108. What That Means For You
• Applications are built from lots of components.
• Your source code is just the glue between them.
• We have great tools for managing source code.
• But components are the real bulk of apps.
• So you need to manage components too.
• Otherwise, you will be screwed (some day).

109. The Bottom Line
Pinto and Statopan make it so easy
there is little reason not to use them.
