+# This tries to find wordcode files and automatically re-compile them if
+# at least one of the original files is newer than the wordcode file.
+# This will only work if the original files were added with their full
+# paths or if the names stored in the wordcode files are relative to the
+# directory where the wordcode file is.
+#
+# Arguments are the names of wordcode files and directories containing
+# wordcode files that should be checked. If no arguments are given, the
+# directories and wordcode files in $fpath are used.
+#
+# And then there are two options:
+# -t: Only check if there are wordcode files that have to be
+# re-compiled. The return status is zero if there are files
+# that need to be re-compiled and non-zero otherwise.
+# -q: Be quiet, i.e.: only set the return status.
+# -p: If this is given, the arguments are interpreted differently:
+# they should form one or more sets of arguments for zcompile,
+# seperated by `--'. For example:
+#
+# zrecompile -p \
+# -r ~/.zshrc -- \
+# -m ~/.zcompdump -- \
+# ~/zsh/comp.zwc ~/zsh/Completion/*/_* \
+#
+# This makes ~/.zshrc be compiled into ~/.zshrc.zwc if that doesn't
+# exist or if it is older than ~/.zshrc. The wordcode file will be
+# marked for reading instead of mapping. The same is done for
+# ~/.zcompdump and ~/.zcompdump.zwc, but the wordcode file is marked
+# for mapping. The last line re-creates the file ~/zsh/comp.zwc if
+# any of the files matching the given pattern is newer than it.
+#
+# Without the -t option, the return status is zero if all wordcode files
+# that needed re-compilation could be compiled and non-zero if compilation
+# for at least one of the files failed.
