# @ECLASS-VARIABLE: TRINTY_BASE_NO_INSTALL_DOC
# @DESCRIPTION: 
# if set to anything except "no" this variable prevents
# trinity-base_src_install() from installing documentation

# @ECLASS-VARIABLE: TRINTY_LANGS
# @DESCRIPTION: 
# This is a whitespace-separated list of translations this ebuild supports.
# These translations are automatically added to IUSE. Therefore ebuilds must set
# this variable before inheriting any eclasses. To enable only selected
# translations, ebuilds must call enable_selected_linguas().

# @DESCRIPTION: 
# This is a whitespace-separated list of translations this ebuild supports.
# These translations are automatically added to IUSE. Therefore ebuilds must set
# this variable before inheriting any eclasses. To enable only selected
# translations, ebuilds must call enable_selected_linguas().

# @ECLASS-VARIABLE: TRINITY_HANDBOOK
# @DESCRIPTION:
# Set to enable handbook in application. Possible values are 'always', 'optional'
# (handbook USE flag) and 'never'.
# This variable must be set before inheriting any eclasses. Defaults to 'never'.
# Also ensures buildtime and runtime dependencies are met.

# @ECLASS-VARIABLE: TRINITY_EXTRAGEAR_PACKAGING
# @DESCRIPTION:
# Set TRINITY_EXTRAGEAR_PACKAGING=yes before inheriting if the package use extragear-like
# packaging and then supports ${TRINITY_LANGS}, ${TRINITY_DOC_LANGS} and
# ${TRINITY_HANDBOOK} variables. The translations are found in the directory
# pointed by the TEG_PO_DIR variable.

# @ECLASS-VARIABLE: TRINITY_GIT_MIRROR
# @DESCRIPTION:
# User (or ebuild) can select another git mirror if it's needed;
# Defaults to https://mirror.git.trinitydesktop.org/gitea/TDE/

# @ECLASS-VARIABLE: TRINITY_GIT_BRANCH
# @DESCRIPTION:
# Specify git branch for live ebuilds. Default: master

# @ECLASS-VARIABLE: TRINITY_COMMON_DOCS
# @DESCRIPTION:
# Common doc names that were found in trinity project's dirs.
