# @BLURB: Convenience function to run commands verbosely and die on failure
# @DESCRIPTION:
# This eclass provides the 'edo' command, and an 'edob' variant for ebegin/eend,
# which logs the command used verbosely and dies (exits) on failure.
#
# This eclass should be used only where needed to give a more verbose log, e.g.
# for invoking non-standard ./configure scripts, or building objects/binaries
# directly within ebuilds via compiler invocations. It is NOT to be used
# in place of generic 'command || die' where verbosity is unnecessary.
