of the target file, instead of just the target directory.
This allows us to overwrite a generated file from a previous
build cycle. This addresses issue #8
This now expects a directory path to store the generated file(s) in.
This was previously a path with file name. We now always use
the filename, inferred from the input path.
We do this, because the changes in this patch fundamentally
alter the way code is generated by the tool. This will, in some
cases, be incompatible with older versions.
* Performs cleanup and minor code fixes.
* Adds two new command line flags:
* -prefix: This accepts a partial path. It is used when generating
a target function name, as well as the key for the Table of Contents
map (see below). The specified prefix is applied to the input
file name, causing the prefix section to be stripped from the
input file path. E.g.:
```
input: /path/to/foo.x
prefix: /path/to
output: /foo.x
```
* -toc: This is a boolean flag which tells the tool to generate
a table of contents for the generated data files. It creates
a separate 'bindata-toc.go' file, which defines a global map
named `go_bindata`. It then appends an `init` function to the
generated file. This function makes the data function register
itself with the global map.
* Fixes the function names the tool infers from input file names
to include the full path. This fixes potential name collisions
when the same file name is processed from different directories.
For example, we can now safely import the following two files:
```
input file: css/ie/foo.css
output function: css_ie_foo_css()
input file: css/chrome/foo.css
output function: css_chrome_foo_css()
```
