/*
* MANIFEST: use of SCons in project config file to build itself
*
* SCons has a Repository feature, introduced in SCons 0.09, that was
* designed to work well with Aegis.
*/
/*
* The build_command field of the project config file is used to invoke
* the relevant build command. This command tells SCons where to find
* the rules.
*
* Our chicken-and-egg dilemma is this: we want to use the version of
* SCons under development in an Aegis change to build itself. But the
* pieces of SCons are likely only partly in this change, and partly in
* baselines.
*
* Python only imports things on a module-by-module basis--which is to
* say, once it finds __init__.py in a given directory, it assumes that
* all other files in that module are in the same directory. But that's
* not the way Aegis works, because if a file hasn't changed on the
* branch, it will only be in its parent's baseline directory.
*
* Aegis' mechanism for working around this sort of problem is to make
* symlinks to the proper baseline versions of each file, which makes
* it look like everything is in the local tree. That's unattractive,
* though, because we really want to eat our own dog food and use the
* SCons -Y options to pull things from the baseline repositories.
*
* So our solution (suggested by Anthony Roach) is a bootstrap.py script
* that does some Aegis-like searching through the baseline directories
* and makes a bootstrap copy of the version of SCons under development
* that we can use for building. After it makes this copy of SCons, it
* executes it with the same command-line arguments we supplied (and
* setting $SCONS_LIB_DIR to the right directory) so we can use it
* here with command-line options as if it were SCons itself. (Note,
* however, that bootstrap.py only understands the specific command-line
* options already in use here, so if you change the call below to add
* some other SCons options, you may have to modify bootstrap.py to
* recognize them.
*
* The ${Source bootstrap.py} substitution finds bootstrap.py wherever
* it may be in the Aegis baselines.
*
* The long -Y${SUBSTitute...} substitution takes the Aegis baseline
* search path and turns it into the right -Y command-line options for
* SCons.
*
* The rest of the substitutions (${DEVeloper}, etc.) should be obvious.
*
* Look in aesub(5) for more information about command substitutions.
*/

* MANIFEST: example of using rcs in the project config file
*
* The entries for the commands are listed below. RCS uses a slightly
* different model than aegis wants, so some maneuvering is required.
* The command strings in this section assume that the RCS commands ci and co
* and rcs and rlog are in the command search PATH, but you may like to
* hard-wire the paths, or set PATH at the start of each. You should also note
* that the strings are always handed to the Bourne shell to be executed, and
* are set to exit with an error immediately a sub-command fails.
*
* In these commands, the RCS file is kept unlocked, since only the owner will
* be checking changes in. The RCS functionality for coordinating shared
* access is not required.
*
* One advantage of using RCS version 5.6 or later is that binary files are
* supported, should you want to have binary files in the baseline.
*
* The ${quote ...} construct is used to quote filenames which contain
* shell special characters. A minimum of quoting is performed, so if
* the filenames do not contail shell special characters, no quotes will
* be used.
