+fuse-overlayfs
+
+An implementation of overlay+shiftfs in FUSE for rootless containers.
+
+# Limitations:
+Read-only mode is not supported, so it is always required to specify an
+upperdir and a workingdir.
+
+# Usage:
+
+```shell
+$ fuse-overlayfs -o lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
+```
+
+Specify a different UID/GID mapping:
+
+```shell
+$ fuse-overlayfs -o uidmapping=0:10:100:100:10000:2000,gidmapping=0:10:100:100:10000:2000,lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
+```

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
