NAME
stanza - Stanza file format
SYNOPSIS
stanza
DESCRIPTION
A stanza file format is used in conjunction with the libAF(3) stanza file library.
The stanza file syntax rules are as follows: Separate entries by one or more blank lines. A colon (:) terminates a entry name. A newline
terminates an attribute name and value pair. Separate a attribute name and attribute value with an equal sign (=). Separate more than one
attribute value with a comma (,). Entry names and attribute names can contain any printable character, except whitespace, a newline, or
special characters, unless specified appropriately. Entry attribute values can contain any printable character, except a newline or spe-
cial characters, unless specified appropriately. Trailing blanks or tabs are allowed at the beginning or end of lines. A number sign (#)
at the beginning of a line indicates a comment. Comments should be included only at the beginning or the end of an entry.
The syntax for a stanza file entry is as follows:
entry_name:
Attribute1_name = Attribute1_value
Attribute2_name = Attribute2_value
Attribute3_name = Attribute3_value1, Attribute3_value2
.
.
.
The entry_name variable specifies the entry name. The attributes for the entry are specified with the Attribute1_name, Attribute2_name,
and Attribute3_name variables. The values for the attributes are specified with the Attribute1_value, Attribute2_value, Attribute3_value1,
and Attribute3_value2 variables.
Several special quoting characters allow attribute values to contain special values and data representations. If you specify a quoting
character, surround the attribute value with quotes. For example, to specify an octal value use the slash character: 07
