It aims to do this with zero dependencies beyond the programs already
installed on your computer†.
-† The only non‐Posix programs‡ required (other than G·N·U Make itself,
- and optionally Git) are those provided by `libxml2` and `libxslt`.
-On most operating systems, these libraries come pre·installed, but on
- Linux machines the commandline utilities are often packaged
- separately (as **`libxml2-utils`** and **`xsltproc`**), which may
- still need to be installed.
-Additionally, not all Linux distributions bundle all necessary Posix
- programs; on Debian (for example) you may need to separately install
- **`sharutils`** for `uudecode` and `uuencode` and **`pax`** for
- archiving.
-
-‡ This make·file also currently depends on non‐Posix `stat` but
- attempts to handle both the G·N·U and B·S·D variants.
-It expects `xargs` to accept a `-0` option, which, while widely
- supported, is not a part of the Posix standard.
-
-**Note:**
-⛩️📰 书社 requires functionality present in G·N·U Make 3.81 or later,
- and will not work in previous versions, or with other implementations
- of Make.
+† Assuming an operating system with a fairly featureful, and
+ Posix‐compliant, development setup (e·g, macOS).
+In fact, on Linux you will probably need to install a few programs:
+ `libxml2-utils`, `xsltproc`, `sharutils`, and `pax`.
## 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.
+
+### `date`
+
+This is a Posix utility, but ⛩️📰 书社 currently depends on
+ unspecified behaviour.
+When the G·N·U version of `stat` is being used, then the G·N·U version
+ of `date` is also expected.
+
+### `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.
+
+### `stat`
+
+This is not a Posix utility, and nor is it particularly portable.
+To get around incompatibilities, ⛩️📰 书社 attempts to recognize G·N·U
+ `stat` by searching for the string `GNU` when invoked with the
+ `--version` option, and falls back to B·S·D behaviour otherwise.
+
+### `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.
+
+### `xargs`
+
+This is a Posix utility, but ⛩️📰 书社 currently depends on
+ unspecified behaviour.
+It requires support for the `-0` flag, which must disable the special
+ quote and whitespace handling of `xargs` in favour of null‐terminated
+ strings.
+
+### `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.
+
## Basic Usage
Place source files in `sources/` and run `make install` to compile
- `git` (optional; set `GIT=` to disable)
- `grep`
- `ln`
+- `ls`
- `mkdir`
- `mv`
- `od`
contain Ascii white·space, colons (`:`), semis (`;`), pipes (`|`),
bucks (`$`), percents (`%`), hashes (`#`), asterisks (`*`), brackets
(`[` or `]`), erotemes (`?`), backslashes (`\`), or control
- characters, must not begin with a hyphen‐minus (`-`), and must not
- end with a cloparen (`)`).**
+ characters, must not begin with a hyphen‐minus (`-`), must not end
+ with a cloparen (`)`), and must not contain quoted braces (`"{` or
+ `}"`).**
The former characters have the potential to conflict with make syntax,
- a leading hyphen‐minus is confusable for a command‐line argument, and
- a trailing cloparen [activates a bug in G·N·U Make
- 3.81](https://stackoverflow.com/questions/17148468/capturing-filenames-including-parentheses-with-gnu-makes-wildcard-function#comment24825307_17148894).

## Parsers
A plaintext (U·T·F‐8) file will be produced from the text nodes in
the transformation result.
+## Pagination
+
+It is possible to have a single source file produce multiple output
+ files via `<书社:page>` elements, whose `@name` gives the name of the
+ page.
+If a parsed document has a `@书社:destination` which contains `%s`,
+ the `%s` will be replaced with the `@name` for each `<书社:page>` (and
+ removed for the main output).
+Otherwise, the `@name` is inserted before the first period of the
+ filename (or at the end of the filename for those with no period).
+If `<书社:page>`s do not have a `@name`, they are numbered
+ sequentially.
+The destination of pages must be in the same directory as their parent.
+
+Pagination essentially forms a limited convenience for the more
+ sophisticated technique of creating an archive with ⛩️📰 书社 and
+ then unarchiving it.
+Pages are, from Make’s point of view, untracked side·effects of
+ installing the main output, meaning they cannot be targeted directly
+ and will not appear in `make list` or `make listout`.
+They are intended solely for the like of indices and feeds, for which
+ convenience and necessity outweigh their flaws.
