## Nomenclature
In Ascii environments, ⛩️📰 书社 should be written `Shushe`, following
the pinyin transliteration.
+## Prerequisites
+
+In most cases, ⛩️📰 书社 aims to require only functionality which is
+ present in all Posix‐compliant operating systems.
+There are a few exceptions.
+Details on particular programs are given below; if a program is not
+ listed, it is assumed that any Posix‐compliant implementation will
+ work.
+
+### `file`
+
+This is a Posix utility, but ⛩️📰 书社 currently depends on
+ unspecified behaviour.
+It requires support for the following additional options :—
+
+- **`-C`**, when supplied with `-m`, must be useable to compile a
+ `.mgc` magicfile for use with future invocations of `file`.
+
+- **`--files-from`** must be useable to provide a file that `file`
+ should read file·names from, and `-` must be useable in this
+ context to specify the standard input.
+
+- **`--mime-type`** must cause `file` to print the internet media type
+ of the file with no charset parameter.
+
+- **`--separator`** must be useable to set the separator that `file`
+ uses to separate file names from types.
+
+These options are implemented by the
+ [Fine Free File Command](https://darwinsys.com/file/), which is used
+ by most operating systems.
+
+### `git`
+
+This is not a Posix utility.
+Usage of `git` is optional, but recommended (and activated by default).
+To disable it, set `GIT=`.
+
+### `make`
+
+This is a Posix utility, but ⛩️📰 书社 currently depends on
+ unspecified behaviour.
+⛩️📰 书社 requires specifically the G·N·U version of `make`, and
+ depends on functionality present in version 3.81 or later.
+It is not expected to work in previous versions, or with other
+ implementations of Make.
+
+### `pax`
+
+This is a Posix utility, but not included in the Linux Standard Base or
+ installed by default in many distributions.
+Only `ustar` format support is required.
+
+### `uudecode` and `uuencode`
+
+These are Posix utilities, but not included in the Linux Standard Base
+ or installed by default in many distributions.
+The G·N·U [Sharutils](https://www.gnu.org/software/sharutils/) package
+ can be installed to access them.
+
+### `xmlcatalog` and `xmllint`
+
+These are not a Posix utilities.
+They is a part of `libxml2`, but may need to be installed separately
+ (e·g by the name `libxml2-utils`).
+
+### `xsltproc`
+
+This is not a Posix utility.
+It is a part of `libxslt`, but may need to be installed separately.

### Attributes added during parsing
To undo this behaviour, remove the `@itemscope` and `@itemtype`
attributes from the embed during the transformation phase.
+- **`transforms/serialization.xslt`:**
+ Replaces `<书社:serialize-xml>` elements with the (escaped)
+ serialized X·M·L of their contents.
+ This replacement happens during the application phase, after most
+ other transformations have taken place.
+
+ If a `@with-namespaces` attribute is provided, any name·space nodes
+ on the toplevel serialized elements whose U·R·I’s correspond to the
+ definitions of the provided prefixes, as defined for the
+ `<书社:serialize-xml>` element, will be declared using name·space
+ attributes on the serialized elements.
+ Otherwise, only name·space nodes which _differ_ from the definitions
+ on the `<书社:serialize-xml>` element will be declared.
+ The string `#default` may be used to represent the default
+ name·space.
+ Multiple prefixes may be provided, separated by white·space.
+
+ When it comes to name·spaces used internally by ⛩️📰 书社, the
+ prefix used by ⛩️📰 书社 may be declared _in addition to_ the
+ prefix(es) used in the source document(s).
+ It is not possible to selectively only declare one prefix for a
+ name·space to the exclusion of others.
+
+ `<书社:raw-output>` elements may be used inside of
+ `<书社:serialize-xml>` elements to inject raw output into the
+ serialized X·M·L.

The following are recommendations on effective creation of

they appear as the toplevel element in a transformation result, cause
⛩️📰 书社 to produce something other than an X·M·L file.
They are :—
-- **`<书社:raw-text>`:**
- A plaintext (U·T·F‐8) file will be produced from the text nodes in
- the transformation result.
+- **`<书社:archive>`:**
+ Each child element with a `@书社:archived-as` attribute will be
+ archived as a separate file in a resulting tarball (this attribute
+ gives the file name).
+ These elements will be processed the same as the root elements of any
+ other file (e·g, they will be wrapped; they can themselves specify
+ non X·M·L output types, ⁊·c).
+ Other child elements will be ignored.
+
+ If the `<书社:archive>` element is given an `@书社:expanded`
+ attribute, rather than producing a tarball ⛩️📰 书社 will output
+ the directory which expanding the tarball would produce.
+ This mechanism can be used to generate multiple files from a single
+ source, provided all of the files are contained with·in the same
+ directory.
- **`<书社:base64-binary>`:**

Ascii whitespace, be treated as a Base·64 string, which is then
decoded.
+- **`<书社:raw-text>`:**
+ A plaintext (U·T·F‐8) file will be produced from the text nodes in
+ the transformation result.
