+The so-called ``list mode'' makes texdoc list all relevant documentation and

+list mode: if there is only one relevant result, then texdoc opens it in a
 viewer, else it offers you a menu.
 
-Usually, \texdoc shows only the results it considers relevant. If there are no
-``good'' results, it falls back to less relevant results. You can force
-it to show you also ``bad'' results even when there are good ones by
-using the ``showall'' mode. (This implies using a menu rather than starting a
-viewer.)
+By default, texdoc hides the results it considers less relevant (unless it
+finds no relevant result at all). In ``showall'' mode, it always shows all
+results.
 
-You can select the mode with command-line options: use
-©texdoc «option» «name»© with one of the following options: ©-w© or ©--view©
-for view mode, ©-m© or ©--mixed© for mixed mode, ©-l© or ©--list© for list

 \subsection{An overview of how texdoc works}
 
-When you type ©texdoc «keyword»©, texdoc browses the trees containing
-documentation (given by the \href{http://www.tug.org/kpathsea/} {kpathsea}
-variable ©TEXDOCS©), lists all files containing ©«keyword»© in their name
-(including the directory name) and give them a score based on some simple
-heuristics. For example, a file named ©«keyword».pdf©, is good,
-©«keyword»-«lang».pdf© will score higher if your favorite language
-©«lang»© is detected or configured, ©«keyword»-doc© will be preferred over
-©«keyword»whatever©, files in a directory named exactly ©«keyword»© get a
-bonus, etc.
-
-There is also some filtering based on extensions: only files with known
-extensions are listed, and some extensions get a lesser score. Also, there is
-some score adjustments based on keywords; by default, Makefile's get a very
-bad score since they are almost never documentation.\footnote{They often end
-  up in the doc tree, since the source of documentation is often in the same
-  directory as the documentation itself in \TeX\ Live. Other source files are
-  discriminated by extension.}
-
-Then, depending on the mode, the file with the highest score is opened in a
+When you type ©texdoc «keyword»©, texdoc first makes a list of files, from two
+sources:
+\begin{enumerate}
+  \item In the trees containing documentation (given by the
+    \href{http://www.tug.org/kpathsea/} {kpathsea} variable ©TEXDOCS©), it
+    selects all files containing ©«keyword»© in their name (including the
+    directory name);
+  \item In the \texlive Database, it looks for packages named
+    ©«keyword»© or containing a file ©«keyword».«ext»© where ©«ext»© may me
+    ©sty© or ©cls©, and selects all the documentation files from this package.
+\end{enumerate}
+Files are filtered by extension: only files with known extensions may be
+selected.
+
+The selected files are then score according to some simple heuristics.  For
+example, a file named ©«keyword».pdf©, is good, ©«keyword»-«lang».pdf© will
+score higher if your favorite language ©«lang»© is detected or configured,
+©«keyword»-doc© will be preferred over ©«keyword»whatever©, files in a
+directory named exactly ©«keyword»© get a bonus, etc.
+
+Score may also be adjusted base on file extensions or known names (or
+subwords): for example, by default, ©Makefile©s get a very bad score since
+they are almost never documentation.\footnote{They often end up in the doc
+  tree, since the source of documentation is often in the same directory as
+  the documentation itself in \texlive. Other source files are discriminated
+  by extension.}
+
+Finally, depending on the mode, the file with the highest score is opened in a
 viewer, or the list of results is shown. Usually, only results with a positive
-score are displayed, except in showall mode. Result with very bad score (-100
-and below) are never displayed.

+(-100 and below) are never displayed.
 
 \medskip
 
-However, this model works only if the documentation for ©«keyword»© has
-©«keyword»© in its name, which is not always true. The documentation of the
-memoir class is in ©memman.pdf©, for example, but it will be found anyway
-since it is in a directory named memoir. But there are more complicated cases:
-the documentation for mathptmx is in ©psnfss2e.pdf©; how can \texdoc guess
-that? It looks for ©mathptmx.sty© in the \texlive package database and finds
-it in the ©psnfss© package, and then adds the documentation files for this
-package to the results. There are two PDF files: ©psfonts.pdf© and
-©psnfss2e.pdf©, but only the second has a comment from the CTAN
-catalogue\footnote{\url{http://texcatalogue.sarovar.org/} --- most relevant
-  information from the catalogue is included in the \texlive package
-  database.} so it is considered better.
-
-However, sometimes even this doesn't work. For example, suppose you're looking
-for documentation about the standard ©article© \LaTeX\ class. Unfortunately,
-the only file name ©article.pdf© is completely unrelated and the name of the
-real file, ©classes.pdf©, is hard to guess (there are plenty of other
-documentation files in the base ©latex© package). Here comes the notion of
-\emph{alias}: in the default configuration file, article is aliased to
-classes, so that when you type ©texdoc article©, texdoc knows it has to look
-also for classes. Note that texdoc will also look for the original name, and
-that a name can be aliased to more than one new name (since version 0.60).
+This model for searching and scoring is quite efficient, but is unfortunately
+not perfect: texdoc may sometimes need a hint, either to find a relevant file
+or, more likely, to recognize which of the files found is the most relevant.
+
+For example, assume you are looking for the documentation of the shortvrb
+\latex package. Texdoc will find ©shortvrb.sty© in the ©latex© \texlive
+package, but since this package contains a lot of documentation files, none of
+which contains the string ©shortverb©, it will sort them basically at random.
+
+Here comes the notion of \emph{alias}: in the default configuration file,
+©shortvrb© is aliased to ©base/doc©, so that when you type ©texdoc shortvrb©,
+texdoc knows it has to look primarily for ©base/doc©. Note that texdoc will
+also look for the original name, and that a name can be aliased to more than
+one new name.

+0).
+
+Unfortunately, sometimes what follows a dot in a file name is not a ``real''
+extension. This often happens with readme files, for example ©readme.fr© or
+©readme.texlive©. So, in addition to his list of known extensions, texdoc has
+a list of known basenames, by default just ©readme©.
+
+The corresponding settings are ©basename_list© and ©badbasename_list©; both
+are similar to ©ext_list© and ©badext_list©. So, a file will be selected if
+either its extension or its base name is known, and get a lesser score if
+either is known to be ``bad.''
+
+\subsection{Variants}\label{ss-variants}
+
+The documentation for a given package is often found in a file named like
+©«package»-doc©. To handle this properlr, texdoc gives a special score files
+named ©«package»«suffix»© where ©«suffix»© is one element of the list given by
+the configuration setting ©suffix_list©.
 
-Similarly, there are ©basename_list© and ©badbasename_list© parameters: a file
