Is there a portable way to find the full path of a filename that would

The correct answer would be "/bin/echo" but abspath("echo") is just
going to give me <cwd>/echo. I need something that will search through
the PATH like execvp() would. I can do it myself, but I'm surprised that
such a feature is not already readily available somewhere.

Help on function find_executable in module distutils.spawn:
find_executable(executable, path=None)
Try to find 'executable' in the directories listed in 'path' (a
string listing directories separated by 'os.pathsep'; defaults to
os.environ['PATH']). Returns the complete filename or None if not
found.
py> distutils.spawn.find_executable("sc")
'C:\\WINDOWS\\system32\\sc.exe'
