# 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,
# separated 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.
