+
+@itemize
+@item bisect - fnds changes responsible for causing a failure.
+@item bundle - creates a single-source-file version of a source package
+suitable for inclusion in a particular target package
+@item callgraph - a tool for reporting the call graph of a Go program.
+@item compilebench - benchmarks the speed of the Go compiler
+@item deadcode - reports unreachable functions in Go programs
+@item digraph - performs queries over unlabelled directed graphs represented
+in text form
+@item eg - performs example-based refactoring
+@item file2fuzz - converts binary files, such as those used by go-fuzz, to the
+Go fuzzing corpus format
+@item fiximports - fixes import declarations to use the canonical import path
+for packages that have an \"import comment\" as defined by
+https://golang.org/s/go14customimport
+@item fuzz-driver - emits function-signature test code
+@item fuzz-runner - performs test runs using \"fuzz-driver\"
+@item go-contrib-init - helps new Go contributors get their development
+environment set up for the Go contribution process
+@item godex - prints (dumps) exported information of packages or selected
+package objects
+@item goimports - updates Go import lines, adding missing ones and removing
+unreferenced ones
+@item gomvpkg - moves go packages, updating import declarations
+@item gonew - starts a new Go module by copying a template module
+@item goyacc - version of yacc for Go
+@item html2article - takes an HTML file and outputs a corresponding article
+file in present format
+@item present - displays slide presentations and articles
+@item present2md - converts legacy-syntax present files to Markdown-syntax
+present files
+@item splitdwarf - uncompresses and copies the DWARF segment of a Mach-O
+executable into the \"dSYM\" file
+@item ssadump - displays and interprets the SSA form of Go programs
+@item stress - catches sporadic failures
+@item stringer - automates the creation of methods that satisfy the
+@code{fmt.Stringer} interface
+@item toolstash - provides a way to save, run, and restore a known good copy of
+the Go toolchain and to compare the object files generated by two toolchains
