How it works

Preparing the grass source

Firstly you have to create a dir /locale/desc in the source tree of grass; inside of this, you have to create some sudirs:

/tools: it contains the scripts grassdoclang.sh
/$lang: the directories, one per language, containing the translate description.html files
/temp : contains the lstmsg_$lang temp file, which is the row numbers list of pofile msgids, generated by grassmklst.sh script

Usage

Just go into /locale/desc/tools and run grassdoclang.sh
./grassdoclang.sh [options]

Usage: ./grassdoclang.sh [-a] | [-t] [-m] [-h] [-c]

Options:
-a executes the entire script
-t executes only header translation
-m only creates the man pages
-h display this help and exit
-c check for updates and exit

Note:
Option -a excludes other options
If both -t and -m are flagged, either -t and -m options are executed, in this order

How the script works

building full manual

creates in dist.i686-pc-linux-gnu/docs directory the /html_$lang directory
renames description.html files as description_en.html
copy the tranlated files in their respective directories and renames them as description.html
rebuilds the directories of the modules
copies complete html files that were generated by make in /html_$lang
moves all back, renaming description_en.html files as description.html

translating headers

attends to automatic translation of the headers, inside the files contained in the /html_$lang directory

generates lstmsg_$lang, which is the row numbers list of the msgids
defines MSGID and MSGSTR variables, which are the strings of original messages and corresponding translation respectively, taken from .po files
searches the msgid strings in headers of the html file and substitute them with the corresponding translation (msgtr string)
finally, copies the not html files (txt, css, png, jpg) into /doc/html_$lang directory

creating the manpages

in the headers, converts html entities to accents
creates the manpages by the grass script g.html2man
converts manpages encoding to UTF-8 code
converts html entities in accents
