All transformations relying on Shrink converted to generic SSA_TRANSFORM signature.
Generic SSA signature updated to accomodate functors that depend on RESTORE
Removed old signatures
Generic signature implemented for SSA2 passes
Generic signature for XML passes implemented
Explained some of what currently takes place within lambda-free.fun

Specifically, I commented on the newScope function with a summary of its purpose,
and on the Fun branch of the exp function with an explanation of individual steps.
Generic signature for RSSA passes implemented.

Updates to Makefile due to SVN to Git repository conversion.

Remove both .ignore and .gitignore files from to-be-installed directories.

Remove/exclude .git directory (rather than .svn directories) for packaging.
Updates to Debian packaging rules due to SVN to Git repository conversion.

Remove/exclude .git directory (rather than .svn directories) for packaging.
The 'sync-ignore' script is unnecessary for Git repositories.
Updates to bin/clean due to SVN to Git repository conversion.

Git's '.gitignore' files are more sophisticated than CVS's
'.cvsignore' files and SVN's 'svn:ignore' properties.  In particular,
Git's '.gitignore' patterns are cumulative from the root directory to
the current directory and patterns can match both (pathless) file
names and file paths.

Given that it is convenient for 'make clean' to delete ignored files
(via the bin/clean script), there are conflicting desires: one the one
hand, take advantage of Git's richer semantics to specify ignored
files; on the other hand, not require git and a complete MLton git
repository to query ignored files (e.g., for a source release).

The compromise is introduce the bin/ls-ignore script to list the
ignored files of the current directory by constructing a 'find'
expression that matches names of ignored files.  The script supports a
reasonable subset of gitignore(5) semantics, but notably does not
support leading-"!" negated patterns and internal-"/" FNM_PATHNAME
patterns due to the complexity of replicating their semantics.
Rename each .ignore file to a .gitignore file.

After the SVN repository to Git repository conversion, a '.gitignore'
symlink was created for each '.ignore' file
(commit 9eecf8c70a40a2f6f0bc08a05efd9e8731ccabdf).  This was simple
and avoided the need to audit other uses of '.ignore' files.  With
commit 926517ffc4dbdaf16dfffbab09255abe46ab2302, the 'bin/clean' and
'bin/ls-ignore' scripts support a reasonable subset of gitignore(5)
semantics, so there is no need to maintain both .ingore files and
.gitignore symlinks.
Update .gitignore files.

Added leading '/' to most patterns in .gitignore files, in order to
limit the pattern to files in the same directory as the corresponding
.gitignore file.  Exceptions are '*.o' and '*.a' patterns in
'runtime/.gitignore' (in order to exclude object and archive files
anywhere in the 'runtime/' directory hierarchy) and '.cm/' patterns in
'lib/.gitignore', 'mlton/.gitignore', and 'util/cm2mlb/.gitignore' (in
order to exclude SML/NJ derived files).  Also added trailing '/' to
some patterns in .gitignore files, in order to limit the pattern to
directories.
Merge pull request #18 from MatthewFluet/svn-cleanup

Various updates due to SVN to Git conversion.
Sources.cm modified to include scc-funs.sig
Merge pull request #10 from staniels/ssa-transform

Generic signatures for XML/SXML, SSA/SSA2, and RSSA transformation passes.
The 'grab-wiki' script is unnecessary.

Since April 2012, when the old mlton.org VPS went down for good, there
is no MoinMoin wiki at mlton.org to grab.
Disable 'make-pdf-guide' in 'docs' target of top-level Makefile.

In preparation for importing the AsciiDoc-based guide, disable
building 'mlton-guide.pdf' from the old MoinMoin-based guide.
Remove old MoinMoin-based guide.
