A library for 'FilePath' manipulations, using Posix or Windows filepaths
depending on the platform.

Both "System.FilePath.Posix" and "System.FilePath.Windows" provide the
same interface.

Given the example 'FilePath': @\/directory\/file.ext@

We can use the following functions to extract pieces.

* 'takeFileName' gives @\"file.ext\"@

* 'takeDirectory' gives @\"\/directory\"@

* 'takeExtension' gives @\".ext\"@

* 'dropExtension' gives @\"\/directory\/file\"@

* 'takeBaseName' gives @\"file\"@

And we could have built an equivalent path with the following expressions:

* @\"\/directory\" '</>' \"file.ext\"@.

* @\"\/directory\/file" '<.>' \"ext\"@.

* @\"\/directory\/file.txt" '-<.>' \"ext\"@.

Each function in this module is documented with several examples,
which are also used as tests.

Here are a few examples of using the @filepath@ functions together:

/Example 1:/ Find the possible locations of a Haskell module @Test@ imported from module @Main@:

@['replaceFileName' path_to_main \"Test\" '<.>' ext | ext <- [\"hs\",\"lhs\"] ]@

/Example 2:/ Download a file from @url@ and save it to disk:

@do let file = 'makeValid' url
  System.Directory.createDirectoryIfMissing True ('takeDirectory' file)@

/Example 3:/ Compile a Haskell file, putting the @.hi@ file under @interface@:

@'takeDirectory' file '</>' \"interface\" '</>' ('takeFileName' file '-<.>' \"hi\")@
