The '#' and ';' characters begin comments to the end of line, +blank lines are ignored. + +The file consists of sections and variables. A section begins with +the name of the section in square brackets and continues until the next +section begins. Section names are not case sensitive. Only alphanumeric +characters, '`-`' and '`.`' are allowed in section names. Each variable +must belong to some section, which means that there must be section +header before first setting of a variable. + +Sections can be further divided into subsections. To begin a subsection +put its name in double quotes, separated by space from the section name, +in the section header, like in example below: + +-------- + [section "subsection"] + +-------- + +Subsection names can contain any characters (doublequote '`"`', backslash +'`\`' and newline have to be entered escaped as '`\"`', '`\\`' and '`\n`', +respecitvely) and are case sensitive. Section header cannot span multiple +lines. Variables may belong directly to a section or to a given subsection. +You can have `[section]` if you have `[section "subsection"]`, but you +don't need to. + +There is also (case insensitive) alternative `[section.subsection]` syntax. +In this syntax subsection names follow the same restrictions as for section +name. + +All the other lines are recognized as setting variables, in the form +'name = value'. If there is no equal sign on the line, the entire line +is taken as 'name' and the variable is recognized as boolean "true". +The variable names are case-insensitive and only alphanumeric +characters and '`-`' are allowed. There can be more than one value +for a given variable; we say then that variable is multivalued. + +Leading and trailing whitespace in a variable value is discarded. +Internal whitespace within a variable value is retained verbatim. + +The values following the equals sign in variable assign are all either +a string, an integer, or a boolean. Boolean values may be given as yes/no, +0/1 or true/false. Case is not significant in boolean values, when +converting value to the canonical form using '--bool' type specifier; +`git-repo-config` will ensure that the output is "true" or "false". + +String values may be entirely or partially enclosed in double quotes. +You need to enclose variable value in double quotes if you want to +preserve leading or trailing whitespace, or if variable value contains +beginning of comment characters (if it contains '#' or ';'). +Double quote '`"`' and backslash '`\`' characters in variable value must +be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'. + +The following escape sequences (beside '`\"`' and '`\\`') are recognized: +'`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB) +and '`\b`' for backspace (BS).
