+=item B<--compilecmd=>I<CMD>
+
+Specifies an alternate shell command to compile (but not install)
+a package.  See the B<installcmd> option for further discussion of
+what this option does and does not do.  If I<CMD> is the empty string,
+B<toast build> uses built-in heuristics to figure out what to do based
+on the package contents.  Otherwise, it will execute I<CMD> as a shell
+command according to Perl's usual conventions, which is to say that
+I<CMD> may contain multiple words, shell metacharacters, and so on.
+I<CMD> will be invoked from the top-level source directory, unless that
+directory contains nothing but a single subdirectory, in which case
+B<toast> will change to that directory first, repeating if necessary.
+A reasonable value for I<CMD> might look something like C<./configure &&
+make>; a similarly reasonable value for the B<installcmd> option might
+be C<make install>.  You probably wouldn't want to specify exactly those
+commands, of course, since B<toast> could figure those out on its own; if
+it tries something fancier instead, the B<noreconfigure> option might do
+what you want.  These options are intended to make it easier to customize
+specific packages; if you encounter a package that won't compile at all
+without them, I'd appreciate a bug report.  If all you really need is to
+pass an extra argument or two to a C<configure> script or set a C<make>
+variable, consider using B<confappend> or B<makeappend> instead.  Default:
+empty string (compile automatically).
+
+=item B<--installcmd=>I<CMD>
+
+Specifies an alternate shell command to install a compiled package.
+This option is analogous to the B<compilecmd> option; see that option's
+description for important details.  B<toast build> always installs a
+package in a separate step immediately after successfully compiling
+it.  The compilation step must not attempt to write to any directory
+outside the source directory (with a few exceptions, such as C</tmp>
+and C</dev/null>).  Before invoking the install command, B<toast build>
+will set a special environment variable, C<DESTDIR>, to the path of a
+private directory tree (containing subdirectories such as C<bin> and
+C<lib>) under which the package should install itself.  In principle,
+the install step should write only to C<DESTDIR>.  If the install step
+attempts to write outside of C<DESTDIR>, the source directory, or a few
+other exceptional filesystem locations, B<toast> may attempt to redirect
+the write to C<DESTDIR> using a variety of means including (but not
+limited to) that described under the B<preload> option.  Because these
+rewriting mechanisms can sometimes be prone to failure, it's best to
+restrict actions taken during the install step to the minimum required.
+Default: empty string (install automatically).
