# The filesystem independent utilities clri, fsdb, dcopy, labelit, and mkfs
# are all built from the source file switchout.c. They are all then links
# to the same object. This is accomplished by:
#	1) building clri from switchout.c (had to choose one)
#	2) installing it in the target directory
#	3) linking the others to clri.
# In a similar manner, ncheck is linked to ff.
