main.goThe code is relatively simple:

package mainimport (    "github.com/derekparker/delve/cmd/dlv/cmds"    "github.com/derekparker/delve/version")// Build is the git sha of this binaries build.var Build stringfunc main() {    version.DelveVersion.Build = Build    cmds.New().Execute()}

mainThe function did two things:
(1) Build Assign the value to the version.DelveVersion member in the variable Build ;
(2) cmds.New() returns one cobra.Command tree , and then invokes the Execute() function to execute the corresponding subcommand, for example dlv version .
