50[+NAME?bldenv - spawn shell for interactive incremental OS-Net
51    consolidation builds]
52[+DESCRIPTION?bldenv is a useful companion to the nightly(1) script for
53    doing interactive and incremental builds in a workspace
54    already built with nightly(1). bldenv spawns a shell set up
55    with the same environment variables taken from an env_file,
56    as prepared for use with nightly(1).]
57[+?In addition to running a shell for interactive use, bldenv
58    can optionally run a single command in the given environment,
59    in the vein of sh -c or su -c. This is useful for
60    scripting, when an interactive shell would not be. If the
61    command is composed of multiple shell words or contains
62    other shell metacharacters, it must be quoted appropriately.]
63[+?bldenv is particularly useful for testing Makefile targets
64    like clobber, install and _msg, which otherwise require digging
65    through large build logs to figure out what is being
66    done.]
67[+?By default, bldenv will invoke the shell specified in
68    $SHELL. If $SHELL is not set or is invalid, csh will be
69    used.]
70[c?force the use of csh, regardless of the  value  of $SHELL.]
71[f?invoke csh with the -f (fast-start) option. This option is valid
72    only if $SHELL is unset or if it points to csh.]
73[d?set up environment for doing DEBUG builds. The default is non-DEBUG,
74    unless the -F flag is specified in the nightly file.]
75[t?set up environment to use the tools in usr/src/tools (this is the
76    default, use +t to use the tools from /opt/onbld)]
