It provides a way to create libraries, so, other people can use your code easily. To create a library, you need to create a package. A package is a collection of related Go source files. Packages are created in directories. The directory name is the package name. Go programs are created in packages, so every Go program is part of a package. A package name should be unique across all of your packages. Package names are always lower case. There are two types of packages: executable and reusable. Executable packages are meant to be compiled and then executed. Reusable packages are meant to be used as dependencies in other programs. To create an executable package, the package name should be main. The main function is the entry point of the executable program. The main function is inside the main package. To create a reusable package, the package name should not be main. The main package is not meant to be used as a dependency. The main package is meant to be compiled and executed. To use a package, you need to import it. There are two ways to import a package. The first way is to import a package with its full path. The second way is to import a package with a local path. The full path of a package is the path from the $GOPATH/src directory to the package directory. The local path of a package is the path from the current directory to the package directory.
