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)]
