# Convert Sun automount map format to amd format

# Package: am-utils-6.x
# Author: Mike Walker <[email protected]>

#
# This program expects maps with the format
#
# dir [ -options ] machine:/path [ # optional comment ]
# ...
#
# and generates an equivalent amd map as follows:
#
# # generated by automountamd on Fri May 21 9:16:56 1993
#
# /defaults \
# type:=nfs;opts:=rw,grpid,nosuid,utimeout=600
#
# dir \
# hostd==machine.larc.nasa.gov;type:=link;fs:=/path || \
# domain==larc.nasa.gov;rhost:=machine;rfs:=/path || \
# rhost:=machine.larc.nasa.gov;rfs:=/path
# ...
#
# You should set the DOMAIN and DEFAULT variables to your preferences.
