# Test starting gdbserver using the 'target remove | ....' syntax.
# The extended-remote target type is tested too.  The test checks that
# the `|` character can be seen in the 'info connections' output, and
# (when Python is available) in the gdb.TargetConnection.details
# string.

# This test relies on starting gdbserver using the pipe syntax.  Not
# sure how well this will run if part of this test is being run
# elsewhere.
