+ About ODS-5 directory names and Perl
+ ------------------------------------
+
+ It seems that the perl function canonpath() in the File::Spec module
+ doesn't treat file specifications where the last directory name
+ contains periods very well.  Unfortunately, some versions of VMS tar
+ will keep the periods in the OpenSSL source directory instead of
+ converting them to underscore, thereby leaving your source in
+ something like [.openssl-1^.1^.0].  This will lead to issues when
+ configuring and building OpenSSL.
+
+ We have no replacement for Perl's canonpath(), so the best workaround
+ for now is to rename the OpenSSL source directory, as follows (please
+ adjust for the actual source directory name you have):
+
+    $ rename openssl-1^.1^.0.DIR openssl-1_1_0.DIR

+ About debugging
+ ---------------
+
+ If you build for debugging, the default on VMS is that image
+ activation starts the debugger automatically, giving you a debug
+ prompt.  Unfortunately, this disrupts all other uses, such as running
+ test programs in the test framework.
+
+ Generally speaking, if you build for debugging, only use the programs
+ directly for debugging.  Do not try to use them from a script, such
+ as running the test suite.
+
+ *The following is not available on Alpha*
+
+ As a compromise, we're turning off the flag that makes the debugger
+ start automatically.  If there is a program that you need to debug,
+ you need to turn that flag back on first, for example:
+
+    $ set image /flag=call_debug [.test]evp_test.exe
+
+ Then just run it and you will find yourself in a debugging session.
+ When done, we recommend that you turn that flag back off:
+
+    $ set image /flag=nocall_debug [.test]evp_test.exe
+
