 dist_pkgdata_DATA = clean-kr.am clean.am @dots{}
 @end example
 
+If you have a project with lots of data files that sometimes change 
+their names (for example computer games under developement) and you are 
+thinking about telling Automake to install whole directory with its 
+contents like
+
address@hidden
+dist_pkgdata_DATA = my_datadir
address@hidden example
+
+then be warned that it's not possible to do this. You have to specify all filenames
+of files you want to install or distribute. @xref{wildcards, ,Why doesn't Automake support wildcards?}
+for reasoning.
+
+Just remember you can use @code{nobase_} prefix (see @ref{Alternative, , An Alternative 
+Approach to Subdirectories}), which is useful if your data 
+files are organized in subdirectories. If you use it, you can just provide full
+filenames and subdirectories will be created during installation. 
+
+They won't be removed in the uninstall process even if they are empty, though.
+The files will be removed after uninstall (this is due to GNU coding standards). 
+
+You may have temptation to help yourself with writing shell scripts as @code{install-data-local} 
+(see @ref{Extending, , Extending Automake Rules} if you need to inspire yourself)
+to bypass the neccessity of providing all the filenames. Anyway, if you decide to use
+your custom procedures, remember to at least run @code{make distcheck}, that may warn
+you if you forget something.
