<h3>What is the basic syntax?</h3>

<p>You can separate the fields of each line by a comma and optional whitespace, or at least one whitespace. The order of columns is:</p>

<ol>
<li>The booking date in format YYYY-MM-DD,</li>
<li>The account name,</li>
<li>The value if it is a debit,</li>
<li>The value if it is a credit,</li>
<li>The purpose (in the case of a debit, it must start with bill ID and colon),</li>
<li>Optional: "<< Comma-separated list of credit IDs used to pay the debt" or ">> Comma-separated list of bill IDs the booked income is used for", respectively</li>
</ol>

<h4>Multi-line purposes</h4>

<p>Multi-line purposes must either be surrounded by " (escape literal " by doubling it), or started in the next line and terminated with an empty one.</p>
 
<h3>How to book an incoming payment</h3>

<p>In the credit column must be a value greater than 0. Cent must be passed as a decimal part, i.e. "100" really mean 100.00, not 1.00! In the debit column you MAY input a name starting with a letter (otherwise it needs to be just "+"), by which you can refer to a credit in lines below instead of the number.</p>

<h3>How to enter a target credit</h3>

<p>A target credit is defined as initially equal 0.</p>

<h3>How to make an internal debt</h3>

<p>A debit, recognized by an amount in the debit column, can have a target credit name or number in the credit column.</p>

<h3>How to book an outgoing payment</h3>

<p>An outgoing payment must not have a target credit. Leave that field empty.</p>
