+ Validate the string represents an absolute path in the filesystem. This function works
+ for windows and unix style paths.

+ The following values will pass:
+
+ $my_path = "C:/Program Files (x86)/Puppet Labs/Puppet"
+ validate_absolute_path($my_path)
+ $my_path2 = "/var/lib/puppet"
+ validate_absolute_path($my_path2)
+
+
+ The following values will fail, causing compilation to abort:
+
+ validate_absolute_path(true)
+ validate_absolute_path([ 'var/lib/puppet', '/var/foo' ])
+ validate_absolute_path([ '/var/lib/puppet', 'var/foo' ])
+ $undefined = undef
+ validate_absolute_path($undefined)

+ ENDHEREDOC

+ args.each do |arg|

+ # [lib/puppet/file_serving/base.rb](https://github.com/puppetlabs/puppet/blob/master/lib/puppet/file_serving/base.rb)
