The narrowspec is comprised of expressions to match remote files and/or

directories that should be pulled into your client.

The narrowspec has *include* and *exclude* expressions, with excludes always

be excluded even if it also matches an include expression.

Each included or excluded entry is in the format described by

'hg help patterns'.

The options allow you to add or remove included and excluded expressions.
|

If --clear is specified, then all previous includes and excludes are DROPPED

empty and will not match any files.

--import-rules accepts a path to a file containing rules, allowing you to
