-## File
-
-A file path with associated metadata.
-
-The File is one of two important data structures in OpenBR (the Template is the other).
-It is typically used to store the path to a file on disk with associated metadata.
-The ability to associate a key/value metadata table with the file helps keep the API simple while providing customizable behavior.
-
-When querying the value of a metadata key, the value will first try to be resolved against the file's private metadata table.
-If the key does not exist in its local table then it will be resolved against the properties in the global Context.
-By design file metadata may be set globally using Context::setProperty to operate on all files.
-
-Files have a simple grammar that allow them to be converted to and from strings.
-If a string ends with a \c ] or \c ) then the text within the final \c [] or \c () are parsed as comma separated metadata fields.
-By convention, fields within \c [] are expected to have the format <tt>[key1=value1, key2=value2, ..., keyN=valueN]</tt> where order is irrelevant.
-Fields within \c () are expected to have the format <tt>(value1, value2, ..., valueN)</tt> where order matters and the key context dependent.
-The left hand side of the string not parsed in a manner described above is assigned to #name.
-
-Values are not necessarily stored as strings in the metadata table.
-The system will attempt to infer and convert them to their "native" type.
-The conversion logic is as follows:
-
-1. If the value starts with \c [ and ends with \c ] then it is treated as a comma separated list and represented with \c QVariantList. Each value in the list is parsed recursively.
-2. If the value starts with \c ( and ends with \c ) and contains four comma separated elements, each convertable to a floating point number, then it is represented with \c QRectF.
-3. If the value starts with \c ( and ends with \c ) and contains two comma separated elements, each convertable to a floating point number, then it is represented with \c QPointF.
-4. If the value is convertable to a floating point number then it is represented with \c float.
-5. Otherwise, it is represented with \c QString.
-
-Metadata keys fall into one of two categories:
-* \c camelCaseKeys are inputs that specify how to process the file.
-* \c Capitalized_Underscored_Keys are outputs computed from processing the file.
-

+If the key does not exist in its local table then it will be resolved against the properties in the global Context.
+By design file metadata may be set globally using Context::setProperty to operate on all files.
+
+Files have a simple grammar that allow them to be converted to and from strings.
+If a string ends with a **]** or **)** then the text within the final **[]** or **()** are parsed as comma separated metadata fields.
+By convention, fields within **[]** are expected to have the format <tt>[key1=value1, key2=value2, ..., keyN=valueN]</tt> where order is irrelevant.
+Fields within **()** are expected to have the format <tt>(value1, value2, ..., valueN)</tt> where order matters and the key context dependent.
+The left hand side of the string not parsed in a manner described above is assigned to #name.

+# FileList
+
+A convenience class for dealing with lists of files.
+
+## Constructors
+
+### FileList()
+
+Default constructor. Doesn't do anything
+
+### FileList(int n)
+
+Initialize the [FileList](#filelist) with n empty files
+
+### FileList(const <a href=http://doc.qt.io/qt-4.8/qstringlist.html>QStringList</a> &files)
+
+Initialize the [FileList](#filelist) from a list of strings. Each string should have the format "filename[key1=value1, key2=value2, ... keyN=valueN]"
+
+### FileList(const <a href=http://doc.qt.io/qt-4.8/qlist.html>QList</a>&lt;[File](#file)&gt; &files)
+
+Initialize the [FileList](#filelist) from a list of [files](#file).
+
+## Static Functions
+
+### static FileList fromGallery(const [File](#file) &gallery, bool cache = false)
+
+Creates a [FileList](#filelist) from a [Gallery](#gallery). Galleries store one or more [Templates](#template) on disk. Common formats include csv, xml, and gal, which is a unique OpenBR format. Read more about this in the [Gallery](#gallery) section. This function creates a [FileList](#filelist) by parsing the stored gallery based on its format. Cache determines whether the gallery should be stored for faster reading later.
+
+    File gallery("gallery.csv");
+
+    FileList fList = FileList::fromGallery(gallery);
+    fList.flat(); // returns all the files that have been loaded from disk. It could
+                  // be 1 or 100 depending on what was stored.
+
+## Functions
+
+### <a href=http://doc.qt.io/qt-4.8/qstringlist.html>QStringList</a> flat() const
+
+Calls [flat](#qstring-flat-const) on every [File](#file) in the list and returns the resulting strings as a <a href=http://doc.qt.io/qt-4.8/qstringlist.html>QStringList</a>.
+
+    File f1("picture1.jpg"), f2("picture2.jpg");
+    f1.set("Key", QString("Value"));
+
+    FileList fList(QList<File>() << f1 << f2);
+    fList.flat(); // returns ["picture1.jpg[Key=Value]", "picture2.jpg"]
+
+### <a href=http://doc.qt.io/qt-4.8/qstringlist.html>QStringList</a> names() const
+
+Stores the name of every [file](#file) in the list and returns the resulting strings as a <a href=http://doc.qt.io/qt-4.8/qstringlist.html>QStringList</a>.
+
+    File f1("picture1.jpg"), f2("picture2.jpg");

+
+    FileList fList(QList<File>() << f1 << f2);
+    fList.names(); // returns ["picture1.jpg", "picture2.jpg"]
+
+### void sort(const <a href=http://doc.qt.io/qt-4.8/qstring.html>QString</a> &key)
+
+Sorts the [FileList](#filelist) based on the value associated with the given key in each file.
+
+    File f1("1"), f2("2"), f3("3");
+    f1.set("Key", QVariant::fromValue<float>(3));
+    f2.set("Key", QVariant::fromValue<float>(1));
+    f3.set("Key", QVariant::fromValue<float>(2));
+
+    FileList fList(QList<File>() << f1 << f2 << f3);
+    fList.names(); // returns ["1", "2", "3"]

 The brief explanation is that it *reads the image from disk, converts it to grayscale, runs the face detector, runs the eye detector on any detected faces, uses the eye locations to normalize the face for rotation and scale, converts to floating point format, and then embeds it in a PCA subspaced trained on face images*.
 If you are familiar with face recognition, you will likely recognize this as the Eigenfaces \cite turk1991eigenfaces algorithm.
  
 As a final note, the Eigenfaces algorithms uses the Euclidean distance (or L2-norm) to compare templates.
-Since OpenBR expects *similarity* values when comparing templates, and not *distances*, the [DistDistance](plugins.md#distdistance) will return *-log(distance+1)* so that larger values indicate more similarity.

+This tutorial is meant to familiarize you with the ideas, objects and motivations behind OpenBR using some fun examples. **Note:** parts of this tutorial require a webcam.
+
+OpenBR is a C++ library built on top of QT and OpenCV. It can either be used from the command line using the **br** application, or from interfacing with the [C API](#c-api). The command line is the easiest and fastest way to get started and this tutorial will use it for all of the examples.
+
+First, make sure that OpenBR has been installed on your system using the steps described in the [installation section](#install.md). Then open up your terminal or command prompt and enter:
+
+    $ br -gui -algorithm "Open+Show(false)" -enroll 0.webcam
+
+If everything goes well your webcam should have opened up and is streaming. Look you are using OpenBR! Let's talk about what's happening in this command. OpenBR expects flags to be prepended by a *-* and arguments to follow the flags and be separated by spaces. Flags normally require a specific number of flags. All of the possible flags and their values are [documented here](#docs/cl_api.md). Let's step through the individual arguments and values. **-gui** is the flag that tells OpenBR to open up a GUI window. Take a look at the [GUI plugins](#docs/plugins/gui.md) for other plugins that require the **-gui** flag. **-algorithm** is one of the most important flags in OpenBR. It expects one argument called the *algorithm string*. This string determines the pipeline that images and metadata propagate through. Finally, **-enroll** reads files from disk and *enrolls* them into the image pipeline. It takes one input argument (0.webcam in our example) and an optional output argument. OpenBR has a range of formats that can be enrolled into algorithms, some examples include .jpg, .png, .csv, and .xml. .webcam tells OpenBR to enroll frames from the computers webcam.
+
+Let's try a slightly more complicated example, after all OpenBR can do way more then just open webcams! Face detection is normally the first step in a [face recognition](#face recognition) algorithm. Let's do face detection in OpenBR. Open up the terminal again and enter:
  
-## OpenBR in 10 minutes or less!
+    $ br -gui -algorithm "Open+Cvt(Gray)+Cascade(FrontalFace)+Draw+Show(false)" -enroll 0.webcam

The different functionalities of OpenBR are specified by algorithms which are passed in as strings. The algorithm to do face recognition is
  
     $ Open+Cvt(Gray)+Cascade(FrontalFace)+ASEFEyes+Affine(88,88,0.25,0.35)+<Mask+DenseSIFT/DenseLBP+DownsampleTraining(PCA(0.95),instances=1)+Normalize(L2)+Cat>+<Dup(12)+RndSubspace(0.05,1)+DownsampleTraining(LDA(0.98),instances=-2)+Cat+DownsampleTraining(PCA(768),instances=1)>+<Normalize(L1)+Quantize)>+SetMetadata(AlgorithmID,-1):Unit(ByteL1)
  
 Woah, that's a lot! Face recognition is a pretty complicated process! We will break this whole string down in just a second, but first we can showcase one of the founding principles of OpenBR. In the face recognition algorithm there are a series of steps separated by +'s (and a few other symbols but they will all be explained); these steps are called plugins and they are the building blocks of all OpenBR algorithms. Each plugin is completely independent of all of the other plugins around it and each one can be swapped, inserted or removed at any time to form new algorithms. This makes it really easy to test new ideas as you come up with them!
  
-So, now lets talk about the basics of algorithms in OpenBR. We know that algorithms are just a series of plugins joined together using the + symbol. What about the : symbol right at the end of the algorithm however? :'s separate the processing part of the algorithm (also called enrollment or generation), from the evaluation part. OpenBR actually has different types of plugins to handle each part. Plugins to the left are called [transforms](abstractions.md#transform) and plugins to the right are called [distances](abstractions.md#distance). Transforms operate on the images as they pass through the algorithm and distances compare (or find the distance between) the images as they finish, usually constructing a similarity matrix in the process.

-This leads us on a small tangent to discuss how images are handled in OpenBR. OpenBR has two structures dedicated to handling data as it passes through an algorithm, [Files](abstractions.md#file) and [Templates](abstractions.md#template). Files handle metadata, the text and other information that can be associated with an image, and templates act as a container for images (we use OpenCV mats) and files. These templates are passed from transform to transform through the algorithm and are *transformed* (see, the name makes sense!) as they go.

-Great, you now know how data is handled in OpenBR but we still have a lot to cover in that algorithm string! Next lets talk about all of the parentheses next to each plugin. Many plugins have parameters that can be set at runtime. For example, [Cvt](plugins.md#cvttransform) (short for convert) changes the colorspace of an image. For face recognition we want to change it to gray so we pass in Gray as the parameter to Cvt. Pretty simple right? Parameters can either be passed in in the order they appear in the code, or they can use a key-value pairing. Cvt(Gray) is equivalent to Cvt(ColorSpace=Gray), check out the docs for the properties of each plugin.

-The last symbol we need to cover is <>. In OpenBR <> represents i/o. Transforms within these brackets will try and load their parameters from the hard drive if they can (they also still take parameters from the command line as you can see). Plugin i/o won't be covered here because it isn't critically important to making OpenBR work for you out of the gate. Stay tuned for a later tutorial on this.
