Imports of gtrace 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.
container/listPackage list implements a doubly linked list.
crypto/md5Package md5 implements the MD5 hash algorithm as defined in RFC 1321.
encoding/hexPackage hex implements hexadecimal encoding and decoding.
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/buildPackage build gathers information about Go packages.
go/importerPackage importer provides access to export data importers.
go/parserPackage parser implements a parser for Go source files.
go/tokenPackage token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates).
go/typesPackage types declares the data types and implements the algorithms for type-checking of Go packages.
ioPackage io provides basic interfaces to I/O primitives.
io/ioutilPackage ioutil implements some I/O utility functions.
logPackage log implements a simple logging package.
osPackage os provides a platform-independent interface to operating system functionality.
path/filepathPackage filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths.
reflectPackage reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types.
runtimePackage runtime contains operations that interact with Go's runtime system, such as functions to control goroutines.
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.
text/tabwriterPackage tabwriter implements a write filter (tabwriter.Writer) that translates tabbed columns in input into properly aligned text.
unicodePackage unicode provides data and functions to test some properties of Unicode code points.
unicode/utf8Package utf8 implements functions and constants to support text encoded in UTF-8.
unsafePackage unsafe contains operations that step around the type safety of Go programs.
