initial commit

+ Lots of code copied from ek, so didn't have to start from scratch, but
  might mean there are some quirks here and there that made sense in ek
  but not necessarily here.

+                            Release date: 2016-04-29
+
+1. License Grants; No Trademark License
+
+   Subject to the terms of this License, I grant You:
+
+   a) A non-exclusive, worldwide, perpetual, royalty-free, irrevocable
+      copyright license, to reproduce, Distribute, prepare derivative works
+      of, publicly perform and publicly display My Work.
+
+   b) A non-exclusive, worldwide, perpetual, royalty-free, irrevocable
+      patent license under Licensed Patents to make, have made, use, sell,
+      offer for sale, and import Covered Works.
+
+   This License does not grant any rights in My name, trademarks, service
+   marks, or logos.
+
+2. Distribution: General Conditions
+
+   You may Distribute Covered Works, provided that You (i) inform
+   recipients how they can obtain a copy of this License; (ii) satisfy the
+   applicable conditions of sections 3 through 6; and (iii) preserve all
+   Legal Notices contained in My Work (to the extent they remain
+   pertinent). "Legal Notices" means copyright notices, license notices,
+   license texts, and author attributions, but does not include logos,
+   other graphical images, trademarks or trademark legends.
+
+3. Conditions for Distributing Derived Works; Outbound GPL Compatibility
+
+   If You Distribute a Derived Work, You must license the entire Derived
+   Work as a whole under this License, with prominent notice of such
+   licensing. This condition may not be avoided through such means as
+   separate Distribution of portions of the Derived Work.
+
+   If the Derived Work includes material licensed under the GPL, You may
+   instead license the Derived Work under the GPL.
+   
+4. Condition Against Further Restrictions; Inbound License Compatibility
+
+   When Distributing a Covered Work, You may not impose further
+   restrictions on the exercise of rights in the Covered Work granted under
+   this License. This condition is not excused merely because such
+   restrictions result from Your compliance with conditions or obligations
+   extrinsic to this License (such as a court order or an agreement with a
+   third party).
+
+   However, You may Distribute a Covered Work incorporating material
+   governed by a license that is both OSI-Approved and FSF-Free as of the
+   release date of this License, provided that compliance with such
+   other license would not conflict with any conditions stated in other
+   sections of this License.
+
+5. Conditions for Distributing Object Code
+
+   You may Distribute an Object Code form of a Covered Work, provided that
+   you accompany the Object Code with a URL through which the Corresponding
+   Source is made available, at no charge, by some standard or customary
+   means of providing network access to source code.
+
+   If you Distribute the Object Code in a physical product or tangible
+   storage medium ("Product"), the Corresponding Source must be available
+   through such URL for two years from the date of Your most recent
+   Distribution of the Object Code in the Product. However, if the Product
+   itself contains or is accompanied by the Corresponding Source (made
+   available in a customarily accessible manner), You need not also comply
+   with the first paragraph of this section.
+
+   Each direct and indirect recipient of the Covered Work from You is an
+   intended third-party beneficiary of this License solely as to this
+   section 5, with the right to enforce its terms.
+
+6. Symmetrical Licensing Condition for Upstream Contributions
+
+   If You Distribute a work to Me specifically for inclusion in or
+   modification of a Covered Work (a "Patch"), and no explicit licensing
+   terms apply to the Patch, You license the Patch under this License, to
+   the extent of Your copyright in the Patch. This condition does not
+   negate the other conditions of this License, if applicable to the Patch.
+
+7. Nullification of Copyleft/Proprietary Dual Licensing
+
+   If I offer to license, for a fee, a Covered Work under terms other than
+   a license that is OSI-Approved or FSF-Free as of the release date of this
+   License or a numbered version of copyleft-next released by the
+   Copyleft-Next Project, then the license I grant You under section 1 is no
+   longer subject to the conditions in sections 3 through 5.
+
+8. Copyleft Sunset
+
+   The conditions in sections 3 through 5 no longer apply once fifteen
+   years have elapsed from the date of My first Distribution of My Work
+   under this License.
+
+9. Pass-Through
+
+   When You Distribute a Covered Work, the recipient automatically receives
+   a license to My Work from Me, subject to the terms of this License.
+
+10. Termination
+
+    Your license grants under section 1 are automatically terminated if You
+
+    a) fail to comply with the conditions of this License, unless You cure
+       such noncompliance within thirty days after becoming aware of it, or
+
+    b) initiate a patent infringement litigation claim (excluding
+       declaratory judgment actions, counterclaims, and cross-claims)
+       alleging that any part of My Work directly or indirectly infringes
+       any patent.
+
+    Termination of Your license grants extends to all copies of Covered
+    Works You subsequently obtain. Termination does not terminate the
+    rights of those who have received copies or rights from You subject to
+    this License.
+
+    To the extent permission to make copies of a Covered Work is necessary
+    merely for running it, such permission is not terminable.
+
+11. Later License Versions
+
+    The Copyleft-Next Project may release new versions of copyleft-next,
+    designated by a distinguishing version number ("Later Versions").
+    Unless I explicitly remove the option of Distributing Covered Works
+    under Later Versions, You may Distribute Covered Works under any Later
+    Version.

+# FWD
+
+`fwd` is a toy language where the idea is that functions/procedures can never
+return values, instead all computation happens "forward" by heavily utilizing
+closures.
+
+## Why?
+
+Informally: Objects have a lot of context to keep track of, are all references
+valid, who owns what, etc. and there have been lots of approaches to control
+this complexity. This is yet another experiment, based on the idea that we could
+syntactically specify which scope an object is valid in.
+
+Effectively, imagine that instead of being handed an object and a bunch of rules
+about how you're allowed to use it, you just specify what code to run  and let
+some implementer ensure that the context is safe for it.
+
+Eventually I should probably write a better explanation, but this is good enough
+for now.
+
+## How?
+
+Functions don't return values, instead they take some amount of closures to
+execute. One pretty central feature of `fwd` is how these closures are expressed
+syntactically, namely that they can be expressed outside of the function
+argument list. As an example,
+
+```
+give_me_some_object() => obj1;
+insert_something(obj1) => obj2;
+do_something_with(obj2);
+```
+
+`=>` can be thought of as a closure operator, and in this case the body of the
+closure is the rest of the function, so
+```
+give_me_some_object(|obj1|{
+    insert_something(obj1, |obj2|{
+        do_something_with(obj2);
+    }
+});
+```
+
+It's possible to specify the exact scope for a closure as well:
+```
+check_cond(x) => a1 {
+    /* cond was true */
+} => a2 {
+    /* cond was false */
+}
+/* runs after check_cond, not 'within' it */
+```
+
+This 'scoping' in combination with move semantics seems like an easy way to
+syntactically specify both ownership and lifetime of an object,
+no need for lifetime annotations or extra stuff like that.
+At least hopefully, this is still a very rough idea and I wouldn't be surprised
+if I have an excessively optimistic view of this. Will have to play around with
+the compiler as I develop it. Presumably I'll also want references, but they are
+as of yet unimplemented.
+
+
+## Examples
+
+See `examples/`. Currently there's just `uniq.fwd`, which filters out non-unique
+lines from its `stdin`.
+
+
+## Current state
+
+The 'meat' of the project is still unimplemented, that being proper move semantics.
+There's an initial parser and a small generator for C++ so that I can quickly
+get up and running and test out programs. There's also `lib/fwdlib.hpp` which
+acts as a bridge between C++ and `fwd`, and any functions that start with `fwd_`
+are actually just C++ functions. This way I can start experimenting with the
+language even in a very crude state, and I don't have to implement containers or
+generics myself. At the moment I also kick pretty much all type checking to C++,
+eventually I'd probably like to take care of it at a higher level.
+
+## Future
+
+If (big if) this experiment turns out to be useful on some level I'll probably
+slowly try to make it more self-reliant. My target would be systems programming,
+possibly even embedded systems, though I don't yet know if this 'paradigm' is
+powerful enough or if I might need some escape hatches like `unsafe` in Rust.

+# All text after a double hash (##) is considered a comment and is placed in

+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:

+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the configuration

+# text before the first occurrence of this tag. Doxygen uses libiconv (or the
+# iconv built into libc) for the transcoding. See
