# LIBSSH_CHECK_CONFIG ([DEFAULT-ACTION])

# ----------------------------------------------------------

#

# Checks for ssh.  DEFAULT-ACTION is the string yes or no to

# specify whether to default to --with-ssh or --without-ssh.

# If not supplied, DEFAULT-ACTION is no.

#

# The minimal supported SSH library version is 0.6.0.

#

# This macro #defines HAVE_SSH if a required header files are

# found, and sets @SSH_LDFLAGS@, @SSH_CFLAGS@ and @SSH_LIBS@

# to the necessary values.

#

# Users may override the detected values by doing something like:

# SSH_LIBS="-lssh" SSH_CFLAGS="-I/usr/myinclude" ./configure

#

# This macro is distributed in the hope that it will be useful,
