+### Use Cases
 * Share filesystem directory via S3 protocol
 * Proxy S3 requests to S3 storage
 * Simple to deploy S3 server with a single command
 * Protocol compatibility in `posix` allows common access to files via posix or S3 
 
+### Overview
 Versity Gateway, a simple to use tool for seamless inline translation between AWS S3 object commands and storage systems. The Versity Gateway bridges the gap between S3-reliant applications and other storage systems, enabling enhanced compatibility and integration while offering exceptional scalability.
 
 The server translates incoming S3 API requests and transforms them into equivalent operations to the backend service. By leveraging this gateway server, applications can interact with the S3-compatible API on top of already existing storage systems. This project enables leveraging existing infrastructure investments while seamlessly integrating with S3-compatible systems, offering increased flexibility and compatibility in managing data storage.

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      with the Work to which such Contribution(s) was submitted. If You

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your work.

+// Package v4 implements signing for AWS V4 signer
+//
+// Provides request signing for request that need to be signed with
+// AWS V4 Signatures.
+//
+// # Standalone Signer
+//
+// Generally using the signer outside of the SDK should not require any additional
+//
+//	The signer does this by taking advantage of the URL.EscapedPath method. If your request URI requires
+//
+// additional escaping you many need to use the URL.Opaque to define what the raw URI should be sent
+// to the service as.
+//
+// The signer will first check the URL.Opaque field, and use its value if set.
+// The signer does require the URL.Opaque field to be set in the form of:
+//
+//	"//<hostname>/<path>"
+//
+//	// e.g.
+//	"//example.com/some/path"
+//
+// The leading "//" and hostname are required or the URL.Opaque escaping will
+// not work correctly.
+//
+// If URL.Opaque is not set the signer will fallback to the URL.EscapedPath()
+// method and using the returned value.
+//
+// AWS v4 signature validation requires that the canonical string's URI path
+// element must be the URI escaped form of the HTTP request's path.
+// http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
+//
+// The Go HTTP client will perform escaping automatically on the request. Some
+// of these escaping may cause signature validation errors because the HTTP
+// request differs from the URI path or query that the signature was generated.
+// https://golang.org/pkg/net/url/#URL.EscapedPath
+//
+// Because of this, it is recommended that when using the signer outside of the
+// SDK that explicitly escaping the request prior to being signed is preferable,
+// and will help prevent signature validation errors. This can be done by setting
+// the URL.Opaque or URL.RawPath. The SDK will use URL.Opaque first and then
+// call URL.EscapedPath() if Opaque is not set.
+//
+// Test `TestStandaloneSign` provides a complete example of using the signer
+// outside of the SDK and pre-escaping the URI path.

+# VersityGW Backend Specific Options #
+######################################
+
+#########
+# posix #
+#########
+
+# The posix backend translates S3 requests to file access in a local filesystem.
+# The posix backend requires a filesystem that supports extended attributes.
+# The top level directory for the gateway must be provided. All sub directories
+# of the top level directory are treated as buckets, and all files/directories
+# below the "bucket directory" are treated as the objects. The object
+# name is split on "/" separator to translate to posix storage.
+# For example:
+# top level (VGW_BACKEND_ARG): /mnt/fs/gwroot
+# bucket: mybucket
+# object: a/b/c/myobject
+# will be translated into the file /mnt/fs/gwroot/mybucket/a/b/c/myobject
+
+# The VGW_CHOWN_UID and VGW_CHOWN_GID options will enable the gateway to
+# change the ownership of newly created files and directories to the IAM
+# account UID/GID.
+#VGW_CHOWN_UID=false
+#VGW_CHOWN_GID=false
+
+###########
+# scoutfs #
+###########
+
+# The scoutfs backend requires a ScoutFS filesystem type for the backend
+# path. The object to posix name mappings follow the same rules as posix for
+# scoutfs. The glacier mode functionality requires ScoutAM to be configured
+# for tiering data from the ScoutFS filesystem to a mass stroage system.
+# The mass storage system is often one or more tape libraries. Due to the
+# high latency of tape, the glacier mode functionality is designed to
+# give feedback to clients about object state and offer ability to request
+# data to be staged back to disk without the client dealing with long
+# request timeout settings.
+
+# The VGW_SCOUTFS_GLACIER option enables the following Glacier API behavior.
+# GET object:  if file offline, return invalid object state
+# HEAD object: if file offline, set obj storage class to GLACIER
+#              if file offline and staging, x-amz-restore: ongoing-request="true"
+#              if file offline and not staging, x-amz-restore: ongoing-request="false"
+#              if file online, x-amz-restore: ongoing-request="false", expiry-date="Fri, 2 Dec 2050 00:00:00 GMT"
+#              note: this expiry-date is not used but provided for client glacier compatibility
+# ListObjects: if file offline, set obj storage class to GLACIER
+# RestoreObject: add batch stage request to file
+#VGW_SCOUTFS_GLACIER=false
+
+# The VGW_CHOWN_UID and VGW_CHOWN_GID options will enable the gateway to
+# change the ownership of newly created files and directories to the IAM
+# account UID/GID.
+#VGW_CHOWN_UID=false
+#VGW_CHOWN_GID=false
+
+######
+# s3 #
+######
+
+# The s3 backend allows the gateway to forward requests to an S3 compatible
+# service. This allows the gateway to act as a proxy for another S3 service.
+# The backend S3 access is all done with a single configured account. The
+# gateway will manage incoming multi-tenant access with the gateway configured
+# IAM service. This gives stroage admins the ability to manage local gateway
+# accounts while maintaining full control and a single account for the backend
+# S3 service.
+
+# When s3 backend selected, the VGW_S3_ACCESS_KEY and VGW_S3_SECRET_KEY must
+# be defined. The VGW_S3_REGION and VGW_S3_ENDPOINT are optional, and will
+# default to "us-east-1" and "https://s3.amazonaws.com" respectively.
