.SH NAME
go \- tool for managing Go source code
.SH SYNOPSIS
.B go build
.RB [\|\-o
.IR output \|]
.RB [
.IR "build flags"
.RB ]
.RB [
.IR packages
.RB ]
.SH DESCRIPTION
Build compiles the packages named by the import paths,
along with their dependencies, but it does not install the results.

If the arguments are a list of .go files, build treats them as a list
of source files specifying a single package.

When the command line specifies a single main package,
build writes the resulting executable to output.
Otherwise build compiles the packages but discards the results,
serving only as a check that the packages can be built.

The \-o flag specifies the output file name.  If not specified, the
name is packagename.a (for a non-main package) or the base
name of the first source file (for a main package).
.SH OPTIONS

arguments to pass on each 5g, 6g, or 8g compiler invocation
.TP
.B \-ldflags 'flag list'
arguments to pass on each 5l, 6l, or 8l linker invocation
