69[+NAME?bldenv - spawn shell for interactive incremental OS-Net
70    consolidation builds]
71[+DESCRIPTION?bldenv is a useful companion to the nightly(1) script for
72    doing interactive and incremental builds in a workspace
73    already built with nightly(1). bldenv spawns a shell set up
74    with the same environment variables taken from an env_file,
75    as prepared for use with nightly(1).]
76[+?In addition to running a shell for interactive use, bldenv
77    can optionally run a single command in the given environment,
78    in the vein of sh -c or su -c. This is useful for
79    scripting, when an interactive shell would not be. If the
80    command is composed of multiple shell words or contains
81    other shell metacharacters, it must be quoted appropriately.]
82[+?bldenv is particularly useful for testing Makefile targets
83    like clobber, install and _msg, which otherwise require digging
84    through large build logs to figure out what is being
85    done.]
86[+?bldenv is also useful if you run into build issues with the
87    source product or when generating OpenSolaris deliverables.
88    If a source product build is flagged, the environment is set
89    up for building the indicated source product tree, which is
90    assumed to have already been created. If the OpenSolaris
91    deliverables flag (-O) is set in NIGHTLY_OPTIONS, the
92    environment is set up for building just the open source.
93    This includes using an alternate proto area, as well as
94    using the closed binaries in $CODEMGR_WS/closed.skel (which
95    is assumed to already exist).]
96[+?By default, bldenv will invoke the shell specified in
97    $SHELL. If $SHELL is not set or is invalid, csh will be
98    used.]
99[c?force the use of csh, regardless of the  value  of $SHELL.]
100[f?invoke csh with the -f (fast-start) option. This option is valid
101    only if $SHELL is unset or if it points to csh.]
102[d?set up environment for doing DEBUG builds (default is non-DEBUG)]
103[t?set up environment to use the tools in usr/src/tools (this is the
104    default, use +t to use the tools from /opt/onbld)]
105[S]:[option?Build a variant of the source product.
106The value of \aoption\a must be one of the following:]{
107       [+E?build the exportable source variant of the source product.]
108       [+D?build the domestic  source  (exportable + crypt) variant of
109           the source product.]
110       [+H?build hybrid source (binaries + deleted source).]
111       [+O?simulate an OpenSolaris (open source only) build.]
