Packages in a program need not have unique package names,
but there are two reserved package names with special meaning.
The name main indicates a command, not a library.
Commands are built into binaries and cannot be imported.
The name documentation indicates documentation for
a non-Go program in the directory. Files in package documentation
are ignored by the go command.

single directory, the command is applied to a single synthesized
package made up of exactly those files, ignoring any build constraints
