# 'consider' comments copied from 'import-gnulib.config':

# consider using do-release-commit-and-tag
# consider using gendocs
# consider using getdelim
# consider using gethrxtime
# consider using getsubopt (for -D)
# consider using gnu-web-doc-update
# consider using idprov-drop and privset for locate
# consider using long-options
# consider using nproc in xargs
# consider using pmccabe2html
# consider using selinux-h
# consider using gendocs
# consider using sig2str in xargs
# consider using signal (why not: maybe we don't need those features)
# consider using the dev-ino moduile to support -samefile.

# consider removing stpcpy
# We have rpmatch, either use it for -ok and xargs or remove the dependency
# use fileblocks, filemode properly.

# Considered, but no:
# consider using autobuild (the information is not usually interesting for us)
# consider using same-inode (we don't keep a full struct stat for the ref file)

# Modules needed for findutils.
# We need regex to ensure that we can build on platforms like
# Solaris which lack those functions.

# gnulib modules used by this package.
