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