package. All the CPPFLAGS and FFLAGS directives in a package are concatenated
and used to compile Fortran files in that package. All the LDFLAGS directives
in any package in the program are concatenated and used at link time. All the
pkg-config directives are concatenated and sent to pkg-config simultaneously
to add to each appropriate set of command-line flags.

<p>
Go programs are constructed by linking together <i>packages</i>.
A package in turn is constructed from one or more source files
that together declare constants, types, variables and functions
belonging to the package and which are accessible in all files
of the same package. Those elements may be

See src/README.vendor for information on loading vendored packages

If a package has imports, the imported packages are initialized
before initializing the package itself. If multiple packages import
a package, the imported package will be initialized only once.
The importing of packages, by construction, guarantees that there
can be no cyclic initialization dependencies.
More precisely:

limits the impact of these use-after-free bugs by preventing reuse of freed
memory regions until the garbage collector is able to determine that it is
safe. Typically, a use-after-free bug will result in a fault and a helpful
error message, but this package reserves the right to not force a fault on
freed memory. That means a valid implementation of this package is to just
