+# Tuned rules for recommend_profile.

+# Syntax:
+# [PROFILE1]
+# KEYWORD11=RE11
+# KEYWORD21=RE12
+#
+# [PROFILE2]
+# KEYWORD21=RE21
+# KEYWORD22=RE22
+
+# KEYWORD can be:
+# virt            - for RE to match output of virt-what
+# system          - for RE to match content of /etc/system-release-cpe
+# process         - for RE to match running processes. It can have arbitrary
+#                   suffix, all process* lines have to match for the PROFILE
+#                   to match (i.e. the AND operator)
+# /FILE           - for RE to match content of the FILE, e.g.:
+#                   '/etc/passwd=.+'. If file doesn't exist, its RE will not
+#                   match.
+# chassis_type    - for RE to match the chassis type as reported by dmidecode
+# syspurpose_role - for RE to match the system role as reported by syspurpose
+
+# All REs for all KEYWORDs have to match for PROFILE to match (i.e. the AND operator).
+# If 'virt' or 'system' is not specified, it matches for every string.
+# If 'virt' or 'system' is empty, i.e. 'virt=', it matches only empty string (alias for '^$').
+# If several profiles matched, the first match is taken.
+#
+# Limitation:
+# Each profile can be specified only once, because there cannot be
+# multiple sections in the configuration file with the same name
+# (ConfigObj limitation).
+# If there is a need to specify the profile multiple times, unique
+# suffix like ',ANYSTRING' can be used. Everything after the last ','
+# is stripped by the parser, e.g.:
+#
+# [balanced,1]
+# /FILE1=RE1
+#
+# [balanced,2]
+# /FILE2=RE2
+#
+# This will set 'balanced' profile in case there is FILE1 matching RE1 or
+# FILE2 matching RE2 or both.
