$FUNCTION dirs_builtin
$DEPENDS_ON PUSHD_AND_POPD
$SHORT_DOC dirs [-clpv] [+N] [-N]
+Display directory stack.
+
Display the list of currently remembered directories. Directories
find their way onto the list with the `pushd' command; you can get
back up through the list with the `popd' command.
-The -l flag specifies that `dirs' should not print shorthand versions
-of directories which are relative to your home directory. This means
-that `~/bin' might be displayed as `/homes/bfox/bin'. The -v flag
-causes `dirs' to print the directory stack with one entry per line,
-prepending the directory name with its position in the stack. The -p
-flag does the same thing, but the stack position is not prepended.
-The -c flag clears the directory stack by deleting all of the elements.
+Options:
+ -c clear the directory stack by deleting all of the elements
+ -l do not print tilde-prefixed versions of directories relative
+ to your home directory
+ -p print the directory stack with one entry per line
+ -v print the directory stack with one entry per line prefixed
