require 'mixlib/versioning/format/semver'

class Versioning
class Format
# Defines the format of the semantic version scheme used for Opscode
# projects. They are SemVer-2.0.0-rc.1 compliant, but we further
# constrain the allowable strings for prerelease and build
# signifiers for our own internal standards.
#
# SUPPORTED FORMATS
# -----------------
# ```text
# MAJOR.MINOR.PATCH
# MAJOR.MINOR.PATCH-alpha.INDEX
# MAJOR.MINOR.PATCH-beta.INDEX
# MAJOR.MINOR.PATCH-rc.INDEX
# MAJOR.MINOR.PATCH-alpha.INDEX+YYYYMMDDHHMMSS
# MAJOR.MINOR.PATCH-beta.INDEX+YYYYMMDDHHMMSS
# MAJOR.MINOR.PATCH-rc.INDEX+YYYYMMDDHHMMSS
# MAJOR.MINOR.PATCH-alpha.INDEX+YYYYMMDDHHMMSS.git.COMMITS_SINCE.SHA1
# MAJOR.MINOR.PATCH-beta.INDEX+YYYYMMDDHHMMSS.git.COMMITS_SINCE.SHA1
# MAJOR.MINOR.PATCH-rc.INDEX+YYYYMMDDHHMMSS.git.COMMITS_SINCE.SHA1
# ```
#
# EXAMPLES
# --------
# ```text
# 11.0.0
# 11.0.0-alpha.1
# 11.0.0-alpha1+20121218164140
