# 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.

# The 'edob' command can be used for long running commands, even if
# those commands produce output. The 'edob' command will suppress the
# command's output and only present it if the command returned with a

# @DESCRIPTION:
# Executes 'command' with ebegin & eend with any given arguments and exits
# on failure unless called under 'nonfatal'.
# on failure unless called under 'nonfatal'. This function redirects
# stdout and stderr to a log file. The content of the log file is shown

# If -m <message> is provided, then invokes ebegin with <message>, otherwise
# a default message is used. If -l <log-name> is provided, then <log-name> is
# used to construct the name of the log file where stdout and stderr of the
# command is redirected to.
