Imports of _gen command

PathSynopsis
bufioPackage bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O.
bytesPackage bytes implements functions for the manipulation of byte slices.
flagPackage flag implements command-line flag parsing.
fmtPackage fmt implements formatted I/O with functions analogous to C's printf and scanf.
go/astPackage ast declares the types used to represent syntax trees for Go packages.
go/formatPackage format implements standard formatting of Go source.
go/parserPackage parser implements a parser for Go source files.
go/printerPackage printer implements printing of AST nodes.
go/tokenPackage token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates).
golang.org/x/tools/go/ast/astutilPackage astutil contains common utilities for working with the Go AST.
ioPackage io provides basic interfaces to I/O primitives.
logPackage log implements a simple logging package.
math/bitsPackage bits implements bit counting and manipulation functions for the predeclared unsigned integer types.
osPackage os provides a platform-independent interface to operating system functionality.
pathPackage path implements utility routines for manipulating slash-separated paths.
regexpPackage regexp implements regular expression search.
runtimePackage runtime contains operations that interact with Go's runtime system, such as functions to control goroutines.
runtime/pprofPackage pprof writes runtime profiling data in the format expected by the pprof visualization tool.
runtime/tracePackage trace contains facilities for programs to generate traces for the Go execution tracer.
sortPackage sort provides primitives for sorting slices and user-defined collections.
strconvPackage strconv implements conversions to and from string representations of basic data types.
stringsPackage strings implements simple functions to manipulate UTF-8 encoded strings.
syncPackage sync provides basic synchronization primitives such as mutual exclusion locks.
