- This instructs the node to relink a child of the given source directory,
- into a different directory and/or to a different name. The source and
- destination directories must be writeable. If {{{to_dir}}} is not present,
- the child link is renamed within the same directory. If {{{to_name}}} is
- not present then it defaults to {{{from_name}}}. If the destination link
- (directory and name) is the same as the source link, the operation has no
- effect.
+ This instructs the node to move a child of the given source directory,
+ into a different directory and/or to a different name. The command is
+ named ``relink`` because it works by adding a new link from the new
+ location, then removing the old link. The source and destination
+ directories must be writeable. If {{{to_dir}}} is not present, the child
+ link is renamed within the same directory. If {{{to_name}}} is not present
+ then it defaults to {{{from_name}}}. If the destination link (directory
+ and name) is the same as the source link, the operation has no effect.
