Class Base

Append path elements to the path 'name' in the 'ENV'
dictionary for this environment.  Will only add any particular
path once, and will normpath and normcase all paths to help
assure this.  This can also handle the case where the env
variable is a list instead of a string.

If delete_existing is 0, a newpath which is already in the path
will not be moved to the end (it will be left where it is).

Append values to existing construction variables
in an Environment, if they're not already there.
If delete_existing is 1, removes existing values first, so
values move to end.

Return a copy of a construction Environment.  The
copy is like a Python "deep copy"--that is, independent
copies are made recursively of each objects--except that
a reference is copied when an object is not deep-copyable
(like a function).  There are no references to any mutable
objects in the original Environment.

Builds the supplied target files from the supplied
source files using the supplied action.  Action may
be any type that the Builder constructor will accept
for an action.

Using the standard Python pretty printer, dump the contents of the
scons build environment to stdout.

If the key passed in is anything other than None, then that will
be used as an index into the build environment dictionary and
whatever is found there will be fed into the pretty printer. Note
that this key is case sensitive.

Directly execute an action through an Environment
        

Search a list of paths for something that matches the prefix and suffix.

paths - the list of paths or nodes.
prefix - construction variable for the prefix.
suffix - construction variable for the suffix.

Use the specified function to parse the output of the command
in order to modify the current environment.  The 'command' can
be a string or a list of strings representing a command and
its arguments.  'Function' is an optional argument that takes
the environment, the output of the command, and the unique flag.
If no function is specified, MergeFlags, which treats the output
as the result of a typical 'X-config' command (i.e. gtk-config),
will merge the output into the appropriate variables.

Parse a mkdep-style file for explicit dependencies.  This is
completely abusable, and should be unnecessary in the "normal"
case of proper SCons configuration, but it may help make
the transition from a Make hierarchy easier for some people
to swallow.  It can also be genuinely useful when using a tool
that can write a .d file, but for which writing a scanner would
be too complicated.

Prepend path elements to the path 'name' in the 'ENV'
dictionary for this environment.  Will only add any particular
path once, and will normpath and normcase all paths to help
assure this.  This can also handle the case where the env
variable is a list instead of a string.

If delete_existing is 0, a newpath which is already in the path
will not be moved to the front (it will be left where it is).

Prepend values to existing construction variables
in an Environment, if they're not already there.
If delete_existing is 1, removes existing values first, so
values move to front.

Replace old_prefix with new_prefix and old_suffix with new_suffix.

env - Environment used to interpolate variables.
path - the path that will be modified.
old_prefix - construction variable for the old prefix.
old_suffix - construction variable for the old suffix.
new_prefix - construction variable for the new prefix.
new_suffix - construction variable for the new suffix.

This function converts a string or list into a list of strings
or Nodes.  This makes things easier for users by allowing files to
be specified as a white-space separated list to be split.
The input rules are:
    - A single string containing names separated by spaces. These will be
      split apart at the spaces.
    - A single Node instance
    - A list containing either strings or Node instances. Any strings
      in the list are not split at spaces.
In all cases, the function returns a list of Nodes and strings.

Initialization of a basic SCons construction environment,
including setting up special construction variables like BUILDER,
PLATFORM, etc., and searching for and applying available Tools.

Note that we do *not* call the underlying base class
(SubsitutionEnvironment) initialization, because we need to
initialize things in a very specific order that doesn't work
with the much simpler base class initialization.
