svn-del.exe removes all .svn directories from a copy
of a development – the PhoneBook project, for example.
...
The method CollectSvns scours all subdirectories from a given root
directory. All sub-directories named .svn are added to the list
of directories that will be deleted. The method is recursive, the
.svn directories are collected in the method's accu, an
argument of CollectSvns.
Each .svn sub-directory in the list is treated in the following
way (method SvnEmptyDelete:
...
Since every .svn directory contains sub-directories, each sub-directory
must be treated in the same way (methods EmptyFiles and DeleteDirectories):
- remove all files after clearing all their attributes (what includes the
read-only attribute) - delete the empty directory
This works recursively, of course. Note that SvnEmptyDelete throws an exception if
the specified root directory is not a directory named .svn. In this regard it
is different from the similar method SvnEmptyDelete.
Another error condition is running svn-del for a directory under C:\Development.
Since this is (by rubicon convention) the development tree with real projects,
not copies of projects, svn-del refuses to work on any directory in that
tree.
