+PKGBUILD parsing
+^^^^^^^^^^^^^^^^
+
+The application provides a house-made shell parser ``ahriman.core.alpm.pkgbuild_parser.PkgbuildParser`` to process PKGBUILDs and extract package data from them. It relies on the ``shlex.shlex`` parser with some configuration tweaks and adds some token post-processing.
+
+#. During the parser process, firstly, it extract next token from the source file (basically, the word) and tries to match it to the variable assignment. If so, then just processes accordingly.
+#. If it is not an assignment, the parser checks if the token was quoted.
+#. If it wasn't then the parser tries to match the array starts (two consecutive tokens like ``array=`` and ``(``) or it is function (``function``, ``()`` and ``{``).
+#. The arrays are processed until the next closing bracket ``)``. After extraction, the parser tries to expand an array according to bash rules (``prefix{first,second}suffix`` constructions).
+#. The functions are just read until the closing bracket ``}`` and then reread whole text from the input string without a tokenization.
+
+All extracted fields are packed as ``ahriman.models.pkgbuild_patch.PkgbuildPatch`` and then can be used as ``ahriman.models.pkgbuild.Pkgbuild`` instance.
+
+The PKGBUILD class also provides some additional functions on top of that:
+
+* Ability to extract fields defined inside ``package*()`` functions, which are in particular used for the multipackages.
+* Shell substitution, which supports constructions ``$var`` (including ``${var}``), ``${var#(#)pattern}``, ``${var%(%)pattern}`` and ``${var/(/)pattern/replacement}`` (including ``#pattern`` and ``%pattern``).
