+== Checking for a symlink's existence == #symlink-exists
+
+Checking for a file's existence is easy:
+
+{{{
+if {[file exists ${f}]} {
+    ...
+}
+}}}
+
+But if `${f}` is a symlink, `file exists` will check for the existence of the file the symlink points to. If you want to check for the existence of the symlink itself, use:
+
+{{{
+if {![catch {file type ${f}}]} {
+    ...
+}
+}}}
