This is a `format' control string that by default should contain two
`%s' conversion specifications: the first will be replaced by the
value of `docbook-xml-source' \(or the empty string, if nil\); the
second will be replaced by the current buffer's file name \(or the
empty string, if nil\).

If `docbook-process-files' is non-nil, the format string should contain
one `%s' conversion specification for each element of its result.

If docbook-process-command is a list, then every element should be a
string.  The strings will be tried in order and %-sequences in the
string will be replaced according to the list below, if the string contains
%-sequences with no replacement value the next string will be tried.

%b means the visited file of the current buffer
%s means the DOCBOOK declaration specified in the docbook-xml-source variable
%d means the file containing the DOCTYPE declaration, if not in the buffer

Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
