 # during a resolve, and if any filter excludes a package, that package is not
 # included in the resolve. Here is a simple example:

-#     package_filter:
-#         excludes:
-#         - glob(*.beta)
-#         includes:
-#         - glob(foo-*)

 # This is an example of a single filter with one exclusion rule and one inclusion
 # rule. The filter will ignore all packages with versions ending in '.beta',
 # except for package 'foo' (which it will accept all versions of). A filter will
-# only exclude a package iff that package matches at least one exclusion rule,
+# only exclude a package if that package matches at least one exclusion rule,
 # and does not match any inclusion rule.
 #
-# Here is another example, which excludes all beta packages, and all packages
-# except 'foo' that are released after a certain date. Note that in order to
-# use multiple filters, you need to supply a list of dicts, rather than just a
-# dict:

 # This example shows why multiple filters are supported - with only one filter,

 # Following are examples of all the possible rules:

 # example             | description
 # --------------------|----------------------------------------------------
 # glob(*.beta)        | Matches packages matching the glob pattern.
 # regex(.*-\\.beta)   | Matches packages matching re-style regex.
-# requirement(foo-5+) | Matches packages within the given requirement.
+# range(foo-5+)       | Matches packages within the given requirement.
 # before(1429830188)  | Matches packages released before the given date.
 # after(1429830188)   | Matches packages released after the given date.
 # *.beta              | Same as glob(*.beta)
