-----------------
The `RECORD` file is composed of records, one line per installed file.
Each record is composed of three elements separated by a `;` character:
Each record is composed of three elements separated by a <tab> character:
- the file's full **path**
- if the installed file is located in a directory in `site-packages`,
it will be a '/'-separated relative path, no matter what is the target
system. This makes this information cross-compatible and allows simple
installation to be relocatable.
- if the installed file is located in the directory where the .egg-info
directory of the package is located, it will be a '/'-separated relative
path, no matter what is the target system. This makes this information
cross-compatible and allows simple installation to be relocatable.
- if the installed file is located elsewhere in the system, a
'/'-separated absolute path is used.

The new functions added in the package are :
- get_projects() -> iterator
Provides an iterator that will return (name, path) tuples, where `name`
is the name of a registered project and `path` the path to its `egg-info`
directory.
- get_egg_info(project_name) -> path or None
Scans all elements in `sys.path` and looks for all directories ending with

Uses `get_egg_info` to get the `PKG-INFO` file, and returns a
`DistributionMetadata` instance that contains the metadata.
- get_files(project_name) -> iterator of (path, hash, size, other_projects)
- get_files(project_name, local=False) -> iterator of (path, hash, size,
other_projects)
Uses `get_egg_info` to get the `RECORD` file, and returns an iterator.
Each returned element is a tuple `(path, hash, size, other_projects)` where
``path``, ``hash``, ``size`` are the values found in the RECORD file.
`path` is the raw value founded in the RECORD file. If `local` is
set to True, `path` will be translated to its real absolute path, using
the local path separator.
`other_projects` is a tuple containing the name of the projects that are
also referring to this file in their own RECORD file (same path).
If `other_projects` is empty, it means that the file is only referred by the
current project. In other words, it can be removed if the project is removed.
- get_egg_info_file(project_name, path) -> file object or None
- get_egg_info_file(project_name, path, binary=False) -> file object or None
Uses `get_egg_info` and gets any element inside the directory,
pointed by its relative path. `get_egg_info_file` will perform
an `os.path.join` on `get_egg_info(project_name)` and `path` to build the
whole path.
`path` can be a '/'-separated path or can use the local separator.
`get_egg_info_file` will automatically convert it using the platform path
separator, to look for the file.
If `binary` is set True, the file will be opened using the binary mode.
Let's use it with our `zlib` example::
