310 * files in the repository as a plain text file with the svn:special
311 * property set. The file contents contain: a platform-specific type
312 * string, a space character, then any information necessary to create
313 * the file on a supported platform. For example, if a symbolic link
314 * were being represented, the repository file would have the
315 * following contents:
317 * "link /path/to/link/target"
319 * Where 'link' is the identifier string showing that this special
320 * file should be a symbolic link and '/path/to/link/target' is the
321 * destination of the symbolic link.
323 * Special files are stored in the text-base exactly as they are
324 * stored in the repository. The platform specific files are created
325 * in the working copy at EOL/keyword translation time using
326 * svn_subst_copy_and_translate2(). If the current platform does not
327 * support a specific special file type, the file is copied into the
328 * working copy as it is seen in the repository. Because of this,
329 * users of other platforms can still view and modify the special
330 * files, even if they do not have their unique properties.
332 * New types of special files can be added by:
333 * 1. Implementing a platform-dependent routine to create a uniquely
334 * named special file and one to read the special file in
336 * 2. Creating a new textual name similar to
337 * SVN_SUBST__SPECIAL_LINK_STR in libsvn_subr/subst.c.
338 * 3. Handling the translation/detranslation case for the new type in
