# show-all:
# Prints a list of (hopefully) all pkgsrc variables that are visible
# to the user or the package developer. It is intended to give
# interested parties a better insight into the inner workings of
# pkgsrc. Each variable name is prefixed with a "category":
#
# * "usr" for user-settable variables,
# * "pkg" for package-settable variables,
# * "sys" for system-defined variables.
#
# CAVEAT: Some few variable values that are shown here may be
# misleading. For example, make(1)'s := operator leaves references
# to undefined variables as-is, so they may be resolved later. So
# if you want to take a snapshot of the exact value of a variable,
# you have to use "snapshot!=printf %s ''${var:q}" instead of
# "snapshot:=${var}".
#
# Keywords: debug show _vargroups
#
# The following types of variables are categorized:
#
# _USER_VARS.*
# Variables that can be set by the user and whose primary file is
# this file.
#
# _PKG_VARS.*
# Variables that can be set by the package and whose primary file
# is this file.
#
# _SYS_VARS.*
# Variables that are defined by this file and that are intended to
# be used by packages.
#
# _DEF_VARS.*
# All variables that are defined by this file, whether internal or
# not, primary or not.
#
# _USE_VARS.*
# All variables that are used by this file, whether internal or
# not, primary or not.
